change the number (1 to 100) to what ever you want and then click the operation to get the answer. (No, now you can do any number you want except 67 because it will literally break your computer)
If you want to go over 100 use the remix https://scratch.mit.edu/projects/1187463114/ credits to @Marshall68039 for figuring out how to do numbers bigger than 100 (Now, you can go over hundred on mine too, but I still recommend going to his.)
