Real numbers are simply the combination of Whole numbers, Integers, Rational and Irrational numbers in the number system.

Suppose a, b, and c is three real numbers.

Distributive Property of Multiplication

Property: $ \text{a}  (  -  \text{b}  +  \text{c}  )  =  \text{a}  ·  (-  \text{b}  \text{)}  +  \text{a}  ·  \text{c}  \text{=}    -  \text{a}  ·  \text{b}    +  \text{a}  ·  \text{c} $
