### Instruction:
Bert made 12 sandwiches for his trip. On the first day, he ate half of the sandwiches he made. The next day he ate 2 sandwiches less. How many sandwiches does Bert have left after these two days?

### 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.
