Answer:
-17
Step-by-step explanation:
At the very first,
4 is multiplied by -1 so it becomes -4
and similarly others also become -3 and -10
then when two negative numbers are added then the negative value increases i.e their negativeness increases so we add them together with -ve sign.
OR
You can understand that we can get -ve sign in common and if we take it out we get to add them together with result in - sign.
And therefore by adding all of them together with -ve sign, we get,
-(4+3+10)
-(17)
