Respuesta :

4+3(7+4 * 2) -100
4+3(15)-100
4+45-100
49-100
-51

Answer:

- 51

Step-by-step explanation:

Order of operations. What's in the parenthesis is first.

4 + 3 ( 7+4 x 2) - 100  

Concentrate on (7 + 4 x 2 ) first.

We multiply first so 4 x 2 = 8  then we add.

(7 + 8) = 15

4 + 3(15) - 100    Again, we multiply first.

4 + 45 - 100      Now we can add and subtract in any order.

49 - 100 = - 51
