__MULTIPLYING__

EG1) -5 x -4 = 20**Because it is a minus x a minus so it equals a +number.**

**EG2) -7 x 8 = -56**

**Because it is a minus x a +number it equals a minus.**

__DIVIDING__

EG1) -24 divided by -8 = 3**Because it is a minus x a minus so it equals a +number.**

**EG2) -20 divided by 10 = -2**

Because it is a minus x a +number it equals a minus.

Because it is a minus x a +number it equals a minus.

__ADDING AND SUBTRACTING__

EG1) -5 +-9 = ?**REMEMBER THE RULES!**

The + and - are next to eachother so it turns into a MINUS!

The sum is now -5 -9.

-5 - 9 = -14

The + and - are next to eachother so it turns into a MINUS!

The sum is now -5 -9.

-5 - 9 = -14

**EG2) -9 - (-5) x (+2) = ?**

**REMEMBER THE RULES!**

Do the brackets = -5 x 2 = -10

The new sum is -9 - - 10 .

There is 2 takeaway's!

The takeaway's turn into a plus.

-9 + -10.

-9 + -10 = 1

Do the brackets = -5 x 2 = -10

The new sum is -9 - - 10 .

There is 2 takeaway's!

The takeaway's turn into a plus.

-9 + -10.

-9 + -10 = 1
