<lang inform7>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.</lang>

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.
