Answer 2

Answer:

18

Step-by-step explanation:

35 - {20 + (8 - 4 + 1)}​ =

First we will take the smallest bracket - 8 - 4 + 1, following the BODMAS rule, we will first do 4 + 1 = 5, then, 8 - 5 = 3.

Then the bracket bigger than that one, 20 + 3 = 17.

And then, at last, the biggest bracket, 35 - 17 = 18.

So, the answer is 18.
