**Additive inverse**- Two numbers whose sum is 0 are additive inverses of one another. Example: 3/4 and -3/4 are additive inverses.**Multiplicative Inverse**- Two numbers whose products is 1 are multiplicative inverses of one another. Example: 3/4 and 4/3 are multiplicative inverses.**Absolute Values**- The distance between a number and zero on the number line. The symbol for absolute value is shown in this equation |-8| = 8.**Integers**- A number expressible in the form a or -a for some whole number a. The set of whole numbers and their opposites (-3, -2, -1, 0, 1, 2, 3)**Long Division**- Standard procedure suitable for dividing simple or complex multi-digit numbers. It breaks down a division problem into a series of easier steps.**Natural Numbers**- The set of numbers (1, 2, 3, 4, ...). Natural numbers can also be called counting numbers.**Opposite Numbers**- Two different numbers that have the same absolute value. Example: 4 and -4.**Positive Numbers**- The set of numbers greater than zero.**Rational Numbers**- The set of numbers that can be written in the form a/b where a and b are integers and b does not equal zero.**Repeating Decimals**- A decimal number in which a digit or group of digits repeats without end.**Terminating Decimals**- A decimal that contains a finite number of digits.**Zero Pair**- Pair of numbers whose sum is zero.
