Evaluate the expression
21 + 32 ÷ 42
Step 1:
We follow the order of operations rule PEMDAS,
Here there are no parentheses.
Step 2:
So, first we evaluate the term with an exponent.
21 + 32 ÷ 42 =
21 + 32 ÷ 16
Step 3:
We do division
21 + 32 ÷ 16 =
21 + 2 =
Step 4:
We then do addition
21 + 2 = 23
Step 5:
So 21 + 32 ÷ 42 = 23
Evaluate the expression
(13 − 11)4 ÷ 4
Step 1:
We follow the order of operations rule PEMDAS,
Step 2:
So, first we evaluate the expression within parentheses (13 − 11)
(13 − 11)4 ÷ 4
(2)4 ÷ 4
Step 3:
Next we evaluate the term with an exponent
(2)4 ÷ 4 =
16 ÷ 4 =
Step 4:
We do division
16 ÷ 4 = 4
Step 5:
So (13 − 11)4 ÷ 4 = 4
