### 5/5 — Very clever!

*2018-09-28, version 1.4*

This is one of those typical “Think of a number” puzzles, where you have to multiply by this, add that, divide by that, take another number away, etc., and the answer always works out to the same number, thus making it unrepeatable...except this doesn’t! No number is keyed is, you just tap the screen between each instruction, yet it gives a different end result each time, which is the answer the user arrives at! No idea how it does this...
