The question
Question: work out 28 ÷ (1 + 3).
28 ÷ (1 + 3)
1 Brackets first
Everyone uses the same order, so we all get the same answer.
Brackets come first.
Order: ( ) → × ÷ → + −
1 plus 3 is 4.
= 28 ÷ 4
2 Times and divide
28 divided by 4 is 7.
= 7
So the answer is 7.
Let's look back.
First: brackets.
Last: times and divide.
Answer
= 7
