The question
Question: work out 5 + 4 × 2.
5 + 4 × 2
1 Times and divide
Times comes before plus.
Order: ( ) → x² √ → × ÷ → + −
4 times 2 is 8.
= 5 + 8
2 Plus and minus
5 plus 8 is 13.
= 13
Careful!
Many people go from left to right and get 18.
But times and divide come before plus and minus.
Careful: not 5 + 4 × 2 = 18 ✗
So the answer is 13.
Let's look back.
First: times and divide.
Last: plus and minus.

= 13
