(Natural) (Whole) (Integer) (Rational) Irrational, (Real Number)

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.

Real Numbers

Numbers that aren't imaginary...

Rational - It is rational because it repeats.

2.125

Rational - It is rational because it terminates.

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)
