Minecraft Calculator - 8Bit

Hi People,

First of all , sry for my english, im from Germany and try to write anything in english :)

So now to my Project, ive build an very big Calculator
and that only with Redstone in minecraft Vanilla.

But before you download it please make sure that when you calculate with (-)
than you must begin with the lower number and than with the bigger number because
it can´t calculate with negativ numbersThis Calculator can only calculate with ( - , + , x) .
and it calculate max. 99x99 , 99+99, 99x99 or 99-99.

I Hope you have FUUUUUN!!!!
