- Terms
- The parts of an expression that are added together
- Like Terms
- Terms that have the same variable parts
- Radicand
- The number or expression inside a radical symbol
- Distributive Property
- Used to find the product of a number and a sum or difference
- Identity Property
- The sum of a number and 0 is the number
- Multiplicative Identity
- 1
- Constant Term
- Has a number but no variable part
- Absolute Value
- The absolute value of a number a is the distance between a and 0 on a number line. lal represents the absolute value of a. When it is negative it then becomes positive
- Whole Numbers
- All numbers excluding negatives and decimals
- Additive Identity
- 0
- Deductive Reasoning
- When you make a conclusion based on statements that are assumed or shown to be true
- Opposites
- 2 numbers that are the same distance from the number line but are on opposite sides of 0
- Perfect Square
- The square of an integer
- Multiplicative Inverse
- The reciprocal of a nonzero number a, written 1/a
- Property of -1
- The product of a number and -1 is the opposite of the number
- Irrational Numbers
- A number that cannot be written as a quotient of 2 integers. The decimal form of the irrational number neither terminates or repeats
- Coefficients
- The number part of a term with a variable
- Equivalent Expressions
- 2 expressions that have the same value for all values of the variable
- Real Numbers
- Set of all rational and irrational numbers
- Commutative Property
- The order in which you add two numbers does not change the sum
- Integers
- All numbers excluding fractions and decimals
- Associative Property
- The way you group three numbers in a sum does not change the sum
- Property of 0
- The product of a number and 0 is 0
- Inverse Property
- The sum of a number and its opposite is 0
- Rational Numbers
- A number a/b where a and b are integers and b equals to 0
