Example Addition problem:
2 + 2 + 2 + 2 = ?
Ask yourself how many 2's there are.... There are 4 in the addition problem. To turn it into a multiplication problem, you take the original number (2) and multiply it by however many of the number there are....
So,
2 + 2 + 2 + 2 is the same as 2 X 4.

A sum is an answer to an addition problem and a product is an answer to a multiplication problem
A multiplication problem's answer is called a product. For a addition or subtraction problem it is called a sum.
Commutativity only applies to multiplication. Associativity applies to addition.
P.E.M.D.A.S is how i remember it Parentheses Exponent Multiplication Division Addition Subtraction also, whichever comes first in the problem goes first, but this only works with multiplication and division and also addition and subtraction but only multiplication with division and addition with subtraction
"What is 3*(-5)" would be such a problem.
