#### Answer

To solve this we will need to start by first solving the items that have been enclosed by the brackets.
5*10 = 50 after this we will have to rewrite the entire problem as
7+ 50 =57

#### Work Step by Step

According to the order of operations (PEMDAS), what is in the parenthesis is done before addition:
7 + (5 x 10)
After multiplying 5 and 10 you get a product of 50
= 7 + 50
Next, add 7 and 50
= 57
Then, 7 + 50 = 57.
