Question

63-[(-3){-2-8-3}]÷ [3{5+(-2)(-1)}]​

Answer 1

Answer:

2 is the right answer of 63-[(-3){-2-8-3}]÷ [3{5+(-2)(-1)}]

Answer 2

Answer:

63 - [(-3) {-2 -8 -3}] ÷ [ 3 {5 + (-2) (-1)}]

= 63 - [-3 ×(-13)] ÷ [3 {5 + 2}]

= 63 - [39] ÷ [3 × 7]

= 63 - [ 39] ÷ 21

$= 69 - \frac{39}{21} \\ = \frac{1449 - 39}{21} \\ = \frac{1410}{21} \\ = \frac{470}{7}$
