Explanation:
As you can see in first expression both have " - " sign infront of them....so all uh need to do is put that minus sign there and add expression cuz ( - ) and ( - ) will be ( + )
= - 94
In second expression the question
- 1 - ( - 4 )
As we know ( - ) × ( - ) will be ( + ) as it is multiplied so we need to change the sign
- 1 + 4 .............[ ( - ) and ( + ) = ( - ) ] so we need to subtract but the plus sign here has greater number so the sign will be plus ....
= + 3
