I made this after 6 days of tense dreaming... IT'S HERE WITH VARIABLES AND MORE BLOCKS AND OTHER THINGS! When it asks you what you want to do it means what operation you need. Add + Subtract - Divide / Multiply * The rest is pretty self explanatory.
Nothing so just this. BTW it has REALLLY simple code so if you want to do something like a scientific calculator then you can use the format of this. 17/01/16: Added START AGAIN Button
