refers to the value of the digit based on its position

when three or more numbers are added together, and two or more can be grouped together and the sum will be the same 3 + (7 + 29) = (3 + 7) + 29

When multiplying numbers can be regrouped without changing the product (3 x 5) x 6 = 3 x (5 x 6)

commutative property for addition and multiplication

you can add and multiply in any order 3 + 5 = 5 + 3 & 5 x 3 = 3 x 5

when three or more numbers are added together, and two or more can be grouped together and the sum will be the same 3 + (7 + 29) = (3 + 7) + 29

When multiplying numbers can be regrouped without changing the product (3 x 5) x 6 = 3 x (5 x 6)

What is the associative property for addition?

adding 0, or multiplying by 1, does not change a number n + 0 = n n x 1 = n

What is distributive property?

erty the sum of two or more addends multiplied by a number, gives the same answer as distributing the multiplier, multiplying each addend separately and then adding them (the products) together 4(2 + 6) = 4 x 2 + 4 x 6 = 8 + 24

changes from positive to negative or negative to positive

What is the identity property?

adding 0, or multiplying by 1, does not change a number n + 0 = n n x 1 = n

What is a parallelogram?

Parallelograms are quadrilaterals with two pairs of parallel sides and two pairs of angles with the same measure. The opposite sides have the same length, and adjacent angles are supplementary

a quadrilateral with 4 right angles and has two pairs of parallel opposite sides ** a rectangle is sometimes a square (because it doesn't have to be - sides don't have to be equal), but a square is always a rectangle (because it always has 4 right angle

the longest side of a triangle must be shorter than the combined lengths of the two other sides
