When simplifying 5(−2)(9) − 3, a student first subtracted 3 from 9. Is this the correct first step? Explain.

Answer 1

No, you should multiply first.

Explanation:

Use PEMDAS. It means parenthesis, exponents, multiplication and division (left to right), and addition and subtraction (left to right). You should multiply 5*-2, then that product *9, then subtract 3. Hope this helps! :)
