Here I just uploaded this, its an already made calculator thing, you type EXPR$("1+1") and it returns "2" If you use it, you dont need to give me credit for it, all youd do is copy over the functions and it should start working Key in screenshot One issue with this calculator is It doesnt catch things like "5 SIN", it just thinks its SIN(5) This can be an issue sometimes, so its your choice
