### Instruction:
 Bert alifanya sandwich 12 kwa ajili ya safari yake. Siku ya kwanza, alikula nusu ya sandwich alizofanya. Siku inayofuata alikula sandwich 2 chini. Bert ana sandwich ngapi zilizobaki baada ya siku hizi mbili?


### Response:
 Siku ya kwanza, Bert alikula 12 / 2 = <<12/2=6>>6 sandwich.
Siku ya pili alikula 6 - 2 = <<6-2=4>>4 sandwich.
Jumla ya sandwich zilizobaki ni 12 - 6 - 4 = <<12-6-4=2>>2.
