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?

How long is the pen? ** The pen is shorter than the pencil by 2 centimeters, so it's 12 - 2 = <<12-2=10>>10 centimeters long.
How long is the rubber? ** That means the rubber is 10 - 3 = <<10-3=7>>7 centimeters long
What is the total length of the rubber, the pen, and the pencil altogether? ** So all accessories are 7 + 10 + 12 = <<7+10+12=29>>29 centimeters long altogether.
