Properties of Multiplication and Addition

associative property of addition

(8 + 7) + 1 = 8 + (7 + 1)

identity property of addition

3 + 0 = 3

commutative property of multiplication

3 x 9= 9 x 3

commutative property of multiplication

3(6)=6(3)

commutative property of addition

3+6=6+3

commutative property of addition

5 + 4 = 4 + 5

identity property of multiplication

5 x 1 = 5

distributive property of multiplication over addition

5(6+4) = (5x6) + (5+4)

identity property of multiplication

identity property of addition

7+0=7

zero property of multiplication

Multiplying anything by zero equals zero.

operations in math are:

Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction (PLEASE EXCUSE MY DEAR AUNT SALLY)

minuend

The first number in a subtraction problem

commutative property of addition

The order of addends can be changed & the sum remains the same. 3+7=7+3

distributive property of multiplication over addition

a (b + c) = ab + ac

addend

a number that is added to another number

subtrahend

a number that is subtracted

distributive property of multiplication over subtraction

a(b-c)=ab-ac

associative property of addition

changing the grouping of terms will not change the sum, (a + b) + c = a + (b + c)

sum

equal

factor

one of two or more numbers that are multiplied to form a product

product

the answer to a multiplication problem

difference

the answer to a subtraction problem
