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.

That is non-commutativity. Matrix multiplication is non-commutative although addition still is.
You can multiply the answer to see if it's right. same with multiplication, addition, and subtraction. Multiplication, you divide, to check addition, you subtract, and subtract, you add.

in a multiplication problem, you don't have to. in addition & subtraction, you do

Multiplication by an integer is the same as repeated addition.
Addition, sum would be multiplication.
Product is the answer in a multiplication problem; Sum is the answer in an addition problem; Quotient is the answer in a division problem; Difference is the answer in a subtraction problem.
Multiplication is repeated addition. For example if you add 3+3+3, that equals 9. You are adding 3, 3 times, so it becomes the multiplication problem 3x3=9.
