Real numbers include: 1) Rational Numbers, and 2) Irrational Numbers

Rational Numbers: can be represented by a ratio (all fractions, terminating and repeating decimals, natural numbers, whole numbers, and integers).

Irrational Numbers: decimals which are non-terminating and do not have a repeating pattern (√2, π, e, etc).


The following examples are arithmetic problems using "real" numbers:

Example Problems using “Rational” Numbers:

1 + 1 = 2

15÷5 = 3

3/5 - 1/10 = ½

.0012 + .3 = 0.3012


Example Problem using “Irrational” Numbers:

√2 + 3√2

= 4√2

= 4*1.414213562373095048801688724209 69807856967187537694807317667973799....

= 5.65685424949238019520675489683879231427868750150779229270671895196….
