Commutative Property of Addition

• it doesn't matter in what order you multiply numbers. The formula for this property is: a * b = b * a.
• changing the order of addends does not change the sum. Here's an example: 4 + 2 = 2 + 4 ‍
• multiplying the sum of two or more addends by a number produces the same result as when each addend is multiplied individually by the number and the products are added together.
• the largest factor that two or more numbers have in common.

Algebraic Expression

• an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.)
• a single part of an expression, separated by addition or subtraction symbols
• A letter that represents an unknown number. Example: x, a, n, z
• terms whose variables and exponent power are the same.

Term

• A letter that represents an unknown number. Example: x, a, n, z
• an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.)
• terms whose variables and exponent power are the same.
• a single part of an expression, separated by addition or subtraction symbols

Variable

• an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.)
• a single part of an expression, separated by addition or subtraction symbols

Coefficient

• an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.)
• any number or numerical value being multiplied to a variable.
• A letter that represents an unknown number. Example: x, a, n, z
• terms whose variables and exponent power are the same.

Constant

• A letter that represents an unknown number. Example: x, a, n, z
• terms whose variables and exponent power are the same.
• any number or numerical value being multiplied to a variable.
• something unchanging; a number that has a fixed value
