The Babylonians already used a composite-ish system for numbers < 60: They had a different symbol for 10. However, smaller numbers were represented by repeating the unit symbol (which is not very clever). I guess that the least confusing transcript to modern notation would be something like 7, 24 to represent 7 * 60 + 24 = 444
