<human>:  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?
<bot>: How many sandwiches did Bert eat on the first day? ** On the first day, Bert ate 12 / 2 = <<12/2=6>>6 sandwiches.
How many sandwiches did Bert eat on the second day? ** The second day he ate 6 - 2 = <<6-2=4>>4 sandwiches.
How many sandwiches does Bert have left after these two days? ** So in total Bert is left with 12 - 6 - 4 = <<12-6-4=2>>2 sandwiches.
