# I'm Thinking of a Number (plus)

Math story 66 · Word problems · Grade 4 · 0:42

## Read the story

I'm thinking of a number. If I add 295, I get 823.

We work backwards: plus turns into minus.

823 minus 295 is 528. My number is 528.

Check: 528 plus 295 is 823. It works!

**My number plus 148 makes 600. What is my number?**

## Answer and working

Correct! 600 minus 148 is 452.

`600 − 148 = 452`
