2 answers:
Answer:
-3
Step-by-step explanation:
A calculator is useful for this.
__
Inside parentheses, we evaluate the multiplication first.
−1⋅[(3−4⋅7)÷5]−2⋅24÷6
= −1⋅[(3−28)÷5]−2⋅24÷6
Then the addition inside parentheses.
= −1⋅[−25÷5]−2⋅24÷6
Now, we do the division inside parentheses.
= −1⋅[−5]−2⋅24÷6
Then we do the multiplication and division left to right.
= 5−48÷6
= 5−8
Finally, we do the sum.
= -3
