### Instruction:
Adrianna has 10 pieces of gum to share with her friends. There wasn't enough gum for all her friends, so she went to the store to get 3 more pieces of gum. She gave out gum to 11 friends. How many pieces of gum does Adrianna have now?

### Response:
 Baada ya kununua vipande 3 vya gundi, Adrianna ana vipande 10 + 3 = <<10+3=13>>13 vya gundi.
Baada ya kugawa gundi kwa marafiki 11, Adrianna ana vipande 13 - 11 = <<13-11=2>>2 vya gundi vilivyobaki.
