Question: write with math signs: 4 more than triple a number.

4 more than triple a number

1 Change words to math

2 Put it in order

We start with triple a number, then add 4.

So we get 3n + 4.

= 3n + 4

3 Check

Let's check with a number.

Say the number is 10.

4 more than triple 10 is 34.

4 more than triple 10 is 34

And 3(10) + 4 is 34 too.

So 3n + 4 is right!

3(10) + 4 = 34

Let's look back.

First: change words to math.

Then: put it in order.

Last: check.
