<human>:  Manny had 3 birthday cookie pies to share with his 24 classmates and his teacher, Mr. Keith. If each of the cookie pies were cut into 10 slices and Manny, his classmates, and Mr. Keith all had 1 piece, how many slices are left?
<bot>: How many cookie slices are there? ** There is a total of 3 x 10 = <<3*10=30>>30 cookie slices.
How many people ate the cookie pieces? ** There are 24 + 1 + 1 = <<24+1+1=26>>26 people who ate the cookie pieces.
How many cookie slices are left? ** There is 30 - 26 = <<30-26=4>>4 cookie slices left.
