The question
Question: work out 2 + 3² × 2.
2 + 32 × 2
1 Powers
Powers come before plus and times.
Order: ( ) → x² √ → × ÷ → + −
3² means 3 times 3.
32 = 3 × 3 = 9
That is 9.
= 2 + 9 × 2
2 Times and divide
Times comes before plus.
9 times 2 is 18.
= 2 + 18
3 Plus and minus
2 plus 18 is 20.
= 20
So the answer is 20.
Let's look back.
First: powers.
Then: times and divide.
Last: plus and minus.
