Once you attempt the question then PrepInsta explanation will be displayed.
You need to do the operation, or sum, inside the brackets first, 3 + 2, then multiply the answer by 4.
3 + 2 = 5.
4 × 5 = 20
If you ignored the brackets and did the sum 4 × 3 + 2 you would get 14. You can see how the brackets make a difference to the answer.
