13 is a Prime number so only 13 and one can go into it
if i have one friend and i have 13 orios and i want to share with him/her how many would we both get?
answer;we would both get 6 in a half :)
10 + 3 = 13, 4 + 9 = 13, 8 + 5 = 13, 9 + 4 = 13, and 7 + 6 = 13 they all equal 13 if you think that they don't equal 13 you can use a calculator.
1 number goes into 13 and that number is 13
