Answer:

1) 38

2) 49

Step-by-step explanation:

1) 10 + 8 ÷2(4 + 3)

Knowing Pemdas, we do the expression in the parentheses first.

4+3 = 7

The new expression is: 10 + 8 ÷ 2 · 7

Using Pemdas, 8 ÷ 2 is 4.

10 + 4 · 7

10 + 28 = 38.

The answer to #1 is 38.

2)  21 ÷ ( 1 ) ( 3 ) + 0 - 14

21 ÷ 1 = 21

21 · 3 = 63

63 + 0 = 63

63 - 14 = 49

The answer to #2 is 49.
