commutative property of addition
3+6=6+3
commutative property of addition
5 + 4 = 4 + 5
identity property of multiplication
5 x 1 = 5

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
