Multiplication of Integers

Multiplication of integers is the process of repetitive addition including positive and negative numbers or we can simply say integers. When we come to the case multiplication of integers, the following cases must be taken into account:

• Multiplying 2 positive numbers

• Multiplying 2 negative numbers

• Multiplying 1 positive and 1 negative number

When you multiply integers with two positive signs, Positive x Positive = Positive = 2 × 5 = 10.

When you multiply integers with two negative signs, Negative x Negative = Positive = –2 × –3 = 6.

When you multiply integers with one negative sign and one positive sign, Negative x Positive = Negative = –2 × 5 = –10.

Division of Integers

Division of integers involves the grouping of items. It includes both positive numbers and negative numbers. Just like multiplication, the division of integers also involves the same cases.

• Dividing 2 positive numbers

• Dividing 2 negative numbers

• Dividing 1 positive and 1 negative number

When you divide integers with two positive signs, Positive ÷ Positive = Positive → 16 ÷ 8 = 2.

When you divide integers with two negative signs, Negative ÷ Negative = Positive → –16 ÷ –8 = 2.

When you divide integers with one negative sign and one positive sign, Negative ÷ Positive = Negative → –16 ÷ 8 = –2.

I Hope It Helps! :)
