Note that the reason there exists a technique called multiplication is so that we do not have to perform tedious and lengthy series of addition such as the one you have presented. So, you have given us 24 of the number 5 to add. 24 x 5 = 120. (Addition form) 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 120
5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 55
4 + 6 + 6 + 5 + 5 + 4 + 6 + 5 + 5 + 6 + 5 + 5 + 5 + 3 = 70
5 + 5 + 5 + 5 + 5 + 5 = 30
