- Task
- sum
- difference
- product
- integer quotient
- remainder
- exponentiation (if the operator exists)
Don't include error handling.
For quotient, indicate how it rounds (e.g. towards zero, towards negative infinity, etc.).
For remainder, indicate whether its sign matches the sign of the first operand or of the second operand, if they are different.
Bonus: Include an example of the integer `divmod` operator. For example: as in #Haskell, #Python and #ALGOL 68

From the principles of operation: Operands are signed and 32 bits long.
Negative quantities are held in two's-complement form.
Multiplication:
The product of the multiplier (the second operand) and the multiplicand
(the first operand) replaces the multiplicand. Both multiplier and
multiplicand are 32-bit signed integers. The product is always a 64-bit
signed integer and occupies an even/odd register pair.
Division:
The dividend (first operand) is divided by the divisor (second operand)
and replaced by the quotient and remainder. The dividend is a 64-bit
signed integer and occupies the even/odd pair of registers.
A 32-bit signed remainder and a 32-bit signed quotient replace the dividend
in the even-numbered and odd-numbered registers, respectively.
The sign of the quotient is determined by the rules of algebra.
The remainder has the same sign as the dividend.

ALGOL 68R has a non-standard '%:=' operator. This operator is equivalent to the OVERAB operator of the revised report, except it delivers the remainder as a result. So a '/:=' b sets a to the quotient of a%b and returns the remainder of a%b as a result (Note "%" is the division operator in Algol 68, not the modulo operator - it can also be written as OVER). This operator must be "stropped" i.e. enclosed in single quotes. eg.
INT quotient:=355, remainder; remainder := quotient %:= 113;
Sets quotient to 3, remainder to 16.
ALGOL W
The Algol W integer division operator (called div) truncates towards zero.
The result of the modulo operator (called rem) has the sign of the first operand when the operands have different signs.
begin
integer a, b;
write( "Enter 2 integers> " );
read( a, b );
write( "a + b: ", a + b ); % addition %
write( "a - b: ", a - b ); % subtraction %
write( "a * b: ", a * b ); % multiplication %
write( "a / b: ", a div b ); % integer division %
write( "a mod b: ", a rem b ); % modulo %
% the ** operator returns a real result even with integer operands %
% ( the right-hand operand must always be an integer, the left-hand %
% operand can be integer, real or complex ) %

The quotient rounds towards 0 if both inputs are integers or towards negative infinity if either input is floating point. The sign of the remainder is always the same as the sign of the first parameter (dividend).

For division and modulus, Awk should act like C.
Exponentiation's note: With nawk or gawk, $1 ** $2 acts like $1 ^ $2. With mawk, $1 ** $2 is a syntax error. Nawk allows **, but its manual page only has ^. Gawk's manual warns, "The POSIX standard only specifies the use of `^' for exponentiation. For maximum portability, do not use the `**' operator."

Common Lisp's integer division functions are floor, ceiling, truncate, and round. They differ in how they round their quotient.
| The function | rounds its quotient towards |
|---|---|
floor
|
negative infinity |
ceiling
|
positive infinity |
truncate
|
zero |
round
|
the nearest integer (preferring the even integer if the mathematical quotient is equidistant from two integers) |
Each function also returns a remainder as its secondary value, such that
quotient * divisor + remainder = dividend .
(mod a b) and (rem a b) return numbers equal to the secondary values of (floor a b) and (truncate a b), respectively.

DuckDB
DuckDB's interactive mode does not allow for the type of interaction envisioned in the question, so we'll assume that the user has already populated a CSV file, input.tsv, with a pair of integers separated by a comma on each line.
The read_csv_auto() function could be relied on to determine an appropriate DuckDB type to use for the two numbers, but here we'll force them to be stored as HUGEINTs.
SELECT x, y, (x+y), (x-y), (x*y), x // y, mod(x,y), exp(x)
FROM read_csv_auto('rc-arithmetic-integer.txt', header=false,

As F# is a functional language, we can easily create a list of pairs of the string name of a function and the function itself to iterate over printing the operation and applying the function to obtain the result:
do
let a, b = int Sys.argv.[1], int Sys.argv.[2]
for str, f in ["+", ( + ); "-", ( - ); "*", ( * ); "/", ( / ); "%", ( % )] do
printf "%d %s %d = %d\n" a str b (f a b)
For example, the output with the arguments 4 and 3 is:
4 + 3 = 7
4 - 3 = 1
4 * 3 = 12
4 / 3 = 1
4 % 3 = 1

Forth
To keep the example simple, the word takes the two numbers from the stack. /mod returns two results; the stack effect is ( a b -- a%b a/b ).
: arithmetic ( a b -- )
cr ." a=" over . ." b=" dup .
cr ." a+b=" 2dup + .
cr ." a-b=" 2dup - .
cr ." a*b=" 2dup * .
cr ." a/b=" /mod .

Different host systems have different native signed division behavior. ANS Forth defines two primitive double-precision signed division operations, from which the implementation may choose the most natural to implement the basic divide operations ( / , /mod , mod , */ ). This is partly due to differing specifications in the two previous standards, Forth-79 and Forth-83.
FM/MOD ( d n -- mod div ) \ floored
SM/REM ( d n -- rem div ) \ symmetric
M* ( n n -- d )
In addition, there are unsigned variants.

This demonstrates normal division (which produces rational numbers when possible), div, and mod. div rounds toward negative infinity (defined as floor[x/y]). mod uses the sign of the second number (defined as x - y * floor[x/y]). All operators automatically produce big integers or exact rational numbers when necessary.

Enter Two Numbers is a room.
Numerically entering is an action applying to one number. Understand "[number]" as numerically entering.
The first number is a number that varies.
After numerically entering for the first time:
now the first number is the number understood.
After numerically entering for the second time:
let A be the first number;
let B be the number understood;
say "[A] + [B] = [A + B]."; [operator syntax]
say "[A] - [B] = [A minus B]."; [English syntax]
let P be given by P = A * B where P is a number; [inline equation]
say "[A] * [B] = [P].";
let Q be given by the Division Formula; [named equation]
say "[A] / [B] = [Q].";
say "[A] mod [B] = [remainder after dividing A by B].";
end the story.
Equation - Division Formula
Q = A / B
where Q is a number, A is a number, and B is a number.
This solution shows four syntaxes: mathematical operators, English operators, inline equations, and named equations. Division rounds toward zero, and the remainder has the same sign as the quotient.

endEach infix operator also has a prefix synonym (sum, difference, product, quotient). Sum and product can also have arity greater than two when used in parentheses (sum 1 2 3). Infix operators in general have high precedence; you may need to enclose their arguments in parentheses to obtain the correct expression.

We can use variables with %, which are double inside with no decimal part. These can have 17 digits. Also A%=1.5 make it 2, not 1. This has a tricky situation: A%=1/2 give 1 to A%. We can use FLOOR() or INT() is the same, or CEIL(), and there is a BANK() which is a Banker Round: BANK(2.5)=2 and BANK(3.5)=4.

IntegerTypesM4
Because of the particular nature of M4, the only user-input is the code itself. Anyway the following code can be used:
eval(A+B)
eval(A-B)
eval(A*B)
eval(A/B)
eval(A%B)once saved in a file, e.g. operations.m4:
m4 -DA=4 -DB=6 operations.m4
or using a sort of driver:
define(`A', 4)dnl
define(`B', 6)dnl
include(`operations.m4')Maple
These operations are all built-in. As all operations are exact, there are no rounding issues involved.

local a := readstat( "Input an integer: " ):
local b := readstat( "Input another integer: " ):
printf( "Sum = %d\n", a + b ):

printf( "Quotient = %d\n", iquo( a, b, 'c' ) ):
printf( "Remainder = %d\n", c ); # or irem( a, b )
NULL # quiet return
end proc:Here is an example of calling DoIt.
> DoIt();
Input an integer: 15;
Input another integer: 12;
Sum = 27
Difference = 3
Product = 180
Quotient = 1
Remainder = 3
>Mathematica /Wolfram Language
Mathematica has all the function built-in to handle this task. Example:
a = Input["Give me an integer please!"];
b = Input["Give me another integer please!"];
Print["You gave me ", a, " and ", b];
Print["sum: ", a + b];
Print["difference: ", a - b];
Print["product: ", a b];
Print["integer quotient: ", Quotient[a, b]];
Print["remainder: ", Mod[a, b]];
Print["exponentiation: ", a^b];
gives back for input 17 and 3:
You gave me 17 and 3 sum: 20 difference: 14 product: 51 integer quotient: 5 remainder: 2 exponentiation: 4913
Mathcad
The text below (from "Task Notes" onwards) is pretty well what you will see on a Mathcad worksheet across most versions (eg, Mathcad 15, Mathcad Prime 6.0, and Mathcad Prime 6.0 Express). Mathcad's "whiteboard" interface allows the user to mix formatted text regions with formatted math regions. Text region formatting is fairly arbitrary, individual characters can have their font, font size and bold/italic/underline settings set or changed at will. Math regions use amendable styles to identify variables, functions (normally built-in functions), keywords, system words and units (Mathcad has a units-aware, SI-based quantity system). It really is a simple as 'writing' on the whiteboard.
Task Notes
For quotient, indicate how it rounds (e.g. towards zero, towards negative infinity, etc.).
There is no quotient function in Mathcad, only complex division. We emulate quotient by standard division followed by rounding using both floor, which rounds towards negative infinity, and trunc, which rounds towards zero.
For remainder, indicate whether its sign matches the sign of the first operand or of the second operand, if they are different. We use the Mathcad function mod(x,y), which returns x modulo y, and has the same sign as x.
Instructions
Enter two integers of your choice for Int1 and Int2.
(type into the right hand side of the 'Int1:= ' and 'Int2:=' statements, overwriting or modifying any numbers already there)

MUMPS
Note: M[UMPS] has an operator called "modulo". When both operands are positive numbers, "modulo" has a result that looks a lot like "remainder"; however, there is an important difference.
To better understand the intricacies of "modulo" and how it is different from "remainder", see Donald Knuth's definition (Volume 1 of the "big books"), or find out the beauty of cyclic algebra as formulated by Niels Henrik Abel (August 5, 1802 – April 6, 1829).

raw_input( )Notes: In Python3 raw_input() will be renamed to input() (the old input() built-in will go away, though one could use eval(input()) to emulate the old ... and ill-advised ... behavior). Also a better program would wrap the attempted int() conversions in a try: ... except ValueError:... construct such as:
def getnum(prompt):
while True: # retrying ...
try:
n = int(raw_input(prompt))
except ValueError:
print "Input could not be parsed as an integer. Please try again."\
continue
break
return n
x = getnum("Number1: ")
y = getnum("Number2: ")
...(In general it's good practice to perform parsing of all input in exception handling blocks. This is especially true of interactive user input, but also applies to data read from configuration and other files, and marshaled from other processes via any IPC mechanism).
Python also has the procedure divmod that returns both quotient and remainder. eg
quotient, remainder = divmod(355,113)
Giving a quotient of 3, and a remainder of 16.

All operators automatically produce integers where appropriate (up to twenty decimal digits in the program below),
or numbers in exponential format when necessary. (The REXX default is 9 decimal digits.)
For division that produces a floating point number, the result is rounded to the nearest number that can be expressed
within the current number of decimal digits (in the example program below, it is 20 decimal digits).

- In smart BASIC, The command INTEG is a true integer function providing only the value of the characteristic. The smart BASIC INT command calculates as a rounding function. This differs from some other versions of BASIC.
- smart BASIC automatically inserts spaces ahead of and behind numbers. This can cause unexpected formatting issues when combining output from numeric variables with text. In order to suppress the trailing space, you must use the ampersand (&) to concatenate the numeric value with the following text (in this case, a period at the end of each sentence). In the case of leading spaces, you must convert the numeric value to text using the STR$ command (as with the last line of the code).

This does, however, make it easy to implement addition using negation and subtraction. In this program, we first negate a; then subtract b, and store the result; and finally negate that result, thereby obtaining the sum of the two integers.

Often, these operations would be performed in a different way from what is shown here. For example, to increase the variable "x" by the value of the variable "y", one would write
incr x $yAlso, it's important to surround the arguments to the expr in braces, especially when any of the parts of the expression are not literal constants. Discussion of this is on The Tcler's Wiki.

echo "a mod b = " `expr $a % $b` # same sign as first operandNotes: Using the ` (backtick operators, also available in most Bourne shells via the $(...) syntax) allows us to keep the results on their labels in the most efficient and portable way. The spaces around the operators in the expr command line arguments are required and the shell requires us to quote or escape the * character has shown, to prevent any possible "globbing" --- filename expansion of the * as a wildcard character.
With SUSv3 parameter expansions:
#!/bin/sh
read a; read b;
echo "a+b = $((a+b))"
echo "a-b = $((a-b))"
echo "a*b = $((a*b))"
echo "a/b = $((a/b))" # truncates towards 0
echo "a mod b = $((a%b))" # same sign as first operandNote: spaces inside the $((...)) are optional and not required; the $((...)) can be inside or outside the double quotes, but the `...` expressions from the previous example can also be inside or outside the double quotes.

In Wren the quotient operator '/' does not round but, when the floor method is applied to the result, it rounds to the lower integer.
The sign of the remainder operator '%' matches the sign of the first operand.

x86 Assembly
Input and output would be OS-specific and are not implemented. This routine works on the 16-bit 8086, as well as on its 32-bit and 64-bit successors: it could be trivially modified to perform 32-bit or 64-bit arithmetic on machines where those are supported. The quotient is truncated towards zero; the remainder takes its sign from the first operand.
