Human: A pen is longer than the rubber by 3 centimeters, and shorter than the pencil by 2 centimeters. Considering the pencil is 12 centimeters long, what is the total length of the rubber, the pen, and the pencil altogether? Assistant:
The pen is shorter than the pencil by 2 centimeters, so it's 12 - 2 = 10 centimeters long.
That means the rubber is 10 - 3 = 7 centimeters long
So all accessories are 7 + 10 + 12 = 29 centimeters long altogether.
