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:
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.
Therefore, `18/-3-5 = -11` .
You can also apply the BODMAS rule.According to it,
- Division should be performed first,that is 18/-3 which gives you -6.
- 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
- Hence,the final answer is -11.
To solve 18/-3 -5, first you should divide the fraction by the rule of PEMDAS:
Then you subtract:
-11 is the final answer.
