The question
Question: work out 40 − (3 + 2)².
40 − (3 + 2)2
1 Brackets first
Brackets come first.
Order: ( ) → x² √ → × ÷ → + −
3 plus 2 is 5.
= 40 − 52
2 Powers
Powers come before minus.
5² means 5 times 5.
52 = 5 × 5 = 25
That is 25.
= 40 − 25
3 Plus and minus
40 minus 25 is 15.
= 15
So the answer is 15.
Let's look back.
First: brackets first.
Then: powers.
Last: plus and minus.
