This is a basic calculator engine you can use if you want. Enjoy! :D
Code is all me. SCROLL DOWN PLS IMPORTANT STUFF NOTE: This calculator only clears out when you click the clear button (or if you reload the page I guess). Also, it can't do multiple operations at once (e.g. 1+2+3*4), and you have to click the clear button after you press the equals sign to do another equation.
