Why Was 5 x 3 = 5 + 5 + 5 Marked Wrong
Brett Berry

Well…Multiplication was just introduced to make addition easier, in simple words it is the alternate method of adding the same number again and again. For example: 2+2+2+2+2+2+2+2+2+2=20 and 2*10=20. If you were asked to add 100 2s, it’s really difficult right?? that’s why the multiplication was found or introduced or whatever… so 2*100=200. So, by the way, 5*3 is nothing but adding three 5s, So 5*3=5+5+5. So, i don’t think the answer can be stated wrong???
