does not do PEMDAS unless you put parentheses around what you want to solve first supported signs +, -, (), *, /, x (x variable) press j to calculate after you put in an equation and press q to calculate for a select x cord (use slider) you need to add the * and () sign if you do this 9(x) or 9(2) examples: 2+(x*2) instead of 2+x*2 ((x+2)*(x+3))/((x-3)*(x+13)) instead of (x+2)(x+3)/(x-3)(x+13
hate math, don't wanna do it. so, I made a calculator.
