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.
