The Hardest Games of 24

In elementary school, my class would play a game called 24. The teacher would hold up a card that had 4 numbers on it. Using each number on the card exactly once and only +,-,\div,\times  for operations, the goal was to make the number 24. And do it faster than all the other kids, obviously.

24

2((2 \times 4)+4)=24

A couple days ago, one of my friends gave us a particularly good one. So I thought I’d share the 5 hardest 24 puzzles! Some other people have already gone through the trouble of figuring out which are the most difficult. Enjoy!
