How do you make 13 with four 4s?

Three fours and one half of 4 Or if you mean using only fours and operation signs you develop methods like this: 42 - 4 + (4/4) = 13. In words, four squared (16) take 4 (12), + the sum of 4/4, which is one (13). Obviously, being an prime number, 13 doesn't fit equally into four, so use a combination of different mathematical symbols to change four into many other numbers: 42 = 16 Square Root of four = 2 4! (four factorial) = 24 43 = 64 4/4 = 1 4 + 4 = 8 Combinations of these can be used to make the 13 you're after.
