KATHY has red balloons and blue balloons. She gives away 5 ballons. If she gives away 3 red ballons, how many blue ballons does she give away?

5 - 3 = ?

To find out how many blue balloons Kathy gives away, we need to subtract the number of red balloons she gives away from the total number of balloons she gives away.

Kathy gives away a total of 5 balloons, and out of those 5, 3 are red balloons. Therefore, to find the number of blue balloons she gives away, we subtract 3 from 5.

5 balloons - 3 red balloons = 2 blue balloons.

So, Kathy gives away 2 blue balloons.
