The answer is going to be 29 because
I calculate the sum from starting with (-7+10))
So once I did that it’s 2-3(3-4(3)
Now you multiply the digits
2-3(3-12)
Now you subtract for 3-12
Which is -9 now you have 2-3(-9)
A negative times a negative is a positive
So 2+27=29
That’s how I got my answer. If this helps please give me brainiest and have a wonderful day
