This is the biggest and most technically advanced calculator so far created for Minecraft Pocket Edition. It supports addition, subtraction and numbers ranging from -65535 to 65535. You can make multiple additions to each set of numbers to perform more advanced calculations. The display screen is huge and displays the output answer very quickly for being such an enormous calculating machine.
In this example I decided to perform a simple calculation. First I selected 30000 on the calculator keypad. Then I pressed Subtract. Next I pressed 6000 and then Enter to output the answer on the display screen.
The resulting answer was correct (24000) as you can see down below.
The size of the redstone calculator is simply amazing. Even if a calculator seems like a simple invention it really isn’t that easy to create. Perhaps this will give you an idea of the complexity it involves.
