Multiplying Integers

The integers are combination of the natural numbers (1, 2, 3, ....) and negatives of natural numbers (....., -3, -2, -1) including 0. The set of the integer is viewed as {...-3,  ?2, ?1, 0, 1, 2, 3,  ...} and denoted by $\mathbb{Z}$.


Multiplication of integers is also called as repeated addition of integers. Because multiplication is nothing but adding the same integer again and again.

For example: 2 $\times$ 3 means add 2 three times i.e. 2 + 2 + 2 = 6

Multiplying Integers Examples

Given below are some of the examples on multiplying integers.

Example 1: Multiply: -10 x (-18)

Solution :  

(-10) x (-18) = -4 × -8

       = 32 (Negative * Negative = Positive)

Example 2: Solve: (15) x (3)

Solution :
(15) × (3)
  = 15 × 3

          = 45 (Positive * Positive = Positive)

Example 3: Multiply -12 and 6

Solution :  Given -12 x (6)

         = -12 × 6

         = - 72  ( Negative * Positive = Negative)
