WELCOME TO THE CALCULATOR!!! Type A for addition, S for subtraction, M for multiplication, and D for division. Then, just put in the numbers you want, like 889 + 908, and the program will do the rest.
THANK YOU BOREDOM!!! I COULD NOT HAVE DONE THIS WITHOUT YOU!!! Thanks to @YoshiCreations, his project Average Results Calculator helped me with the idea. ENJOY THE CALCULATOR!!!
