Infinite Calculator

Infinite Calculator is for decisions that come down to a few numbers. Write the calculation once, then make versions of it with different numbers and compare them side by side. Change the venue quote, the ticket price or the deposit and every version recalculates, showing how far it is from the original. Solve Set a target, such as keeping profit at £0, and Solve works out the value each input would need. Answers that break a limit, like a venue's capacity, are flagged. Tap an answer to save it as a new version.
