Question

You and a friend are playing a video game. Your score so far is 340 points, andyour friend's score is -220 points. What is the difference between your scores?

Answer 1

We need to subtract -220 from 340, that is,

`340-(-220)`

By inserting the minus sign into the parenthesis, we have

`340+220`

Therefore, the difference between the scores is 560 points
