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? Give me reasons, before answering the question

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. So the final answer is 29.
