    \[\frac{ -3^3 }{ -3^2 }\] Quotient of Powers: To divide powers with like bases, subtract the exponents. So you'd have: \[-3^1 or -3\]

    But remember that multiplication and division BOTH have the same priority. And addition/subtraction also have the SAME priority. So what if you encounter an expression with both multiplication and division for example? In that case, you would go from left to right.

    (Some people think because it's PEMDAS that you have to exactly follow that order). But bear in mind that there are some mnemonics out there that invert the MD and AS
