How to Divide Integers

It just uses positive and negative numbers instead

For instance: -3x(-4)=12

2x(-4)=-8 Think 2 groups of -4

-5x2=-10 Think the opposite of 5 groups of 2

-3x(-4)=12 Think the opposite of 3 groups of -4

Because division is the inverse of multiplication, the rules for dividing integers are the same as the rules for multiplying integers

Just like multiplying integers you are using positive and negative numbers

For instance -12/3=-4

If the signs are the same, the quotient is positive

24/3=8 -6/(-3)=2

If the signs are different, the quotient is negative

-20/5=-4 72/(-8)=-9

Zero divided by any integer equals 0

0/14=0 0/-11=0

You cannot divide any integer by 0

3x(-2)=?

-6x-4=?

Practice Examples

12/(-3)=?

-15/(-3)=?
