Give examples of problems which involve real numbers.

Real numbers include:

(1) Rational Numbers (can be represented by a ratio), and

(2) Irrational Numbers (√2, π, e, etc)

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….
