Evaluate the following
9 – 8 ÷ 4 + 6 × 3
Step 1:
We follow the rule of order of operations PEMDAS.
There are no parentheses and exponents here.
Step 2:
So we first do all multiplication and division from left to right
9 – 8 ÷ 4 + 6 × 3 =
9 – 2 + 18
Step 3:
We then do all addition and subtraction from left to right
9 – 2 + 18 =
7 + 18 =
25
Step 4:
So 9 – 8 ÷ 4 + 6 × 3 = 25
Evaluate the following
18 ÷ 6 + 2 × 7 – 5
Step 1:
We follow the rule of order of operations PEMDAS.
There are no parentheses and exponents here.
Step 2:
So we first do all multiplication and division from left to right
18 ÷ 6 + 2 × 7 – 5 =
3 + 14 – 5
Step 3:
We then do all addition and subtraction from left to right
3 + 14 – 5 =
17 – 5 = 12
Step 4:
So 18 ÷ 6 + 2 × 7 – 5 = 12
