Step-by-step explanation:
- ( 9 - ( m + a ))
= -( 9 - ( 4 + 3))
= - ( 9 - (7))
= -( 9 - 7)
= - 2
Answer:
-2
Step-by-step explanation:
Open the bracket first
-(9-(m+a))
-(9-m-a)
-9+m+a
So let's substitute the value for the m and a
-9+4+3
Using BODMAS
Addition comes before substration
So
-9+4+3
=-9+7
=-2
So the final answer is-2
