3*(-5)
3x1=3, in this case 3x11=33.
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

One multiplication problem that equals 3235 is ( 65 \times 49 ). Another example is ( 647 \times 5 ). Both of these pairs of numbers, when multiplied, result in 3235.
5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 45, the shorter version is 5*9.
If you put the numbers in order it is: 0, 0, 1, 2, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 6, 6, 7, 7, 7, 7, 8, 9. Since there are 25 numbers, we are looking for the thirteenth number, which is 5.
9*5=45 or 5+5+5+5+5+5+5+5+5=45 or1*5*9=45
