Terminating Decimal
A decimal that comes to a stop (Example: 5.8 or 7.3452)
Repeating Decimal
A decimal that repeats the same digit, or set of digits, without coming to a stop. (Example: 1.3434343434...)
Rational Number
A number that can be written as a ratio (fraction) and decimal form. The decimal form is either repeating or terminating. (REMEMBER: R = REPEATING AND T = TERMINATING... R a T ional
Irrational Numbers
A number that cannot be expressed as a ratio (fraction) In decimal form it is non-repeating and non-terminating but might have some kind of patter. (It is a weird number) (Example: 3.123434321234321112343...)
2.0110100101011010...
Irrational - It is irrational because it has a pattern and does not repeat.

Natural Number
The set of counting numbers (1,2,3...) You learn them when you are a toddler.
Rational
The set of integers including the numbers that can be expressed by a ratio (fraction)
Whole
The set of natural numbers and 0 (0,1,2,3...)
Integers
The set of whole numbers and their opposites (including zero!) (-3,-2,-1,0,1,2,3)
