Step by step
The question
Question: write with math signs: 3 times a number.
3 times a number
1 Change words to math
2 Put it in order
3 × n is written 3n: the number goes in front, with no × sign.
So we get 3n.
= 3n
3 Check
Let's check with a number.
Say the number is 10.
3 times 10 is 30.
3 times 10 is 30
And 3(10) is 30 too.
So 3n is right!
3(10) = 30
Let's look back.
First: change words to math.
Then: put it in order.
Last: check.
Answer
= 3n
