### Instruction:
 Dada yake Sara ana vijitabu 4 vidogo katika kabati lake. Msimu uliopita alinunua vijitabu 6 zaidi na kisha akapoteza 2. Dada yake Sara ana vijitabu vingapi sasa?


### Response:
 Dada yake Sara ana vijitabu 4 katika kabati lake.
Alinunua vijitabu 6 zaidi.
Alipoteza vijitabu 2.
Hivyo sasa dada yake Sara ana vijitabu 4 + 6 - 2 = <<4+6-2=8>>8.
