Distributive Property - the property which states the when two addends are multiplied by a factor when the product is the same as if each addend was multiplied by the factor and those products were added.
Ex.
1. ( 4 x 37) + ( 6 x 37)
= 148 + 222
= 370
2. 37 x ( 4+6)
= 37 x 10
= 370
Ex.
1. ( 4 x 37) + ( 6 x 37)
= 148 + 222
= 370
2. 37 x ( 4+6)
= 37 x 10
= 370
Expressions and Equations
Expression - a number, a variable or any combination of numbers, variables, operation signs, and grouping symbols.
Equation - a mathematical sentence with an equal sign.
Variable - a letter or a symbol that represents a number in an algebraic expression
Equation - a mathematical sentence with an equal sign.
Variable - a letter or a symbol that represents a number in an algebraic expression
Commutative Property - the order of how you arrange them does not matter, the sum will always be the same.
Associative Property - changing the grouping of numbers does not change the sum or product.
Identity Property - the sum of any number and zero is that number.
