The ultimate calculator machine made in just one hour! No alphabet, no negative numbers, (I have the answer at absolute value) and no decimal answers, (they get rounded up). It's a work in progress, but it just might help on your math homework! ;)
1st credit goes to Scratch Tutorials on youtube, (or known as FUNUT) on Scratch, 2nd credit goes to Cysteamine for the idea of a math calculator on Scratch. I hope this works, and it can get upgraded, but that's the best I can do for now. Have fun! Remix, use, and share to friends for use.
