Point M belongs to segment AB. Find the length of the segment MB if AB = 12.3 cm, AM = 7.4 cm.

If point M belongs to segment AB, then it divides this segment into two segments AM and MB. In order to find the length of the segment MB, you need to subtract the length of the segment AM from the length of the segment AB, that is,
