What does find mean? The nth upside down number can be found formulaically so calculating the fifty millionth is no harder than the five millionth.--[[User:Nigel Galloway|Nigel Galloway]] ([[User talk:Nigel Galloway|talk]]) 14:25, 14 February 2023 (UTC)

: '''find''':, ''verb:'', ''detect, discover, locate, observe'' If you are further confused [https://letmegooglethat.com/?q=find+definition maybe this will help]. "The nth upside down number can be found formulaically so calculating the fifty millionth is no harder than the five millionth." Cool. Should be no problem then. 👍 --[[User:Thundergnat|Thundergnat]] ([[User talk:Thundergnat|talk]]) 15:49, 14 February 2023 (UTC)
:: Like [[User:Nigel Galloway|Nigel Galloway]] said, it is easy to calculate the n.th number.<br>
:: Just calculate the upper half in base 9, and add afterwards 1 to each digit<br>
