You use the order of operations to get a final value of 80.

Explanation:

Your expression looks like this

2⋅[−50−(−74−16)]

The order of operations (think PEMDAS) tells you that parantheses come first, followed by exponents, multiplication/divison, and addition/subtraction.

Your expression has two parantheses which must be solved first. The first paranthesis has

(−74−16)=−90

The expression now becomes

2⋅(−50−(−90)]=2⋅(−50+90)

Next comes the second paranthesis

(−50+90)=40

The expression now becomes

2⋅40=80

Therefore,

2⋅[−50−(−74−16)]=80
