# 18/-3-5

To simplify this, apply order of operation PEMDAS.

In the given expression, the operations present are divide and subtract.

As per PEMDAS, division should be perform before subtraction.So it becomes:

`18/-3-5`

`=-6-5`

Then, do subtraction. To subtract -6 and 5, which have unlike signs, change the sign of the second number to its opposite. And change the operation from subtract to add.

`=-6+(-5)`

`=-11`

Therefore,  `18/-3-5 = -11` .

You can also apply the BODMAS rule.According to it,

1. Division should be performed first,that is 18/-3 which gives you -6.
2. Then,proceed to to the next operation which is subtraction,that is
-6-5 .As both are negative,add them both and put negative sign,which means -(6+5)=-11

3. Hence,the final answer is -11.

To solve 18/-3 -5, first you should divide the fraction by the rule of PEMDAS:

`18/-3`

`=-6.`

Then you subtract:

`-6-5 `

`=-11.`

18/-3-5

just in case you mean `(18)/(-3-5)` I'll do that one for you.

The first thing you must do is solve the denominator:
-3 - 5 = -8
therefore the problem is:

`(18)/(-8)`
which is equal to:

` (18)/(-8) = -2.25`
