do you mean pemdas? parenthesis, exponents, multiplication/division, addition/subtraction that is the order in solving an equation example: (#^2 means squared) (x+9)^2 + 2(x + 2) = 1 (x+9)(x+9) + 2(x+2) = 1 foil x^2 + 18x + 81 + 2x + 4 = 1 x^2 + 20x + 85 = 1 subtract 1 x^2 + 20x + 84 then you would finish it. it’s a bad example. but that’s how you do it.
