2 1 point game skills

1, with 3×8=24, 4×6=24, 12×2=24.

Try to sum the four numbers on the card face into 3 and 8, 4 and 6, and then multiply them to solve. For example, 3,3,6 and 10 can form (10-6÷3)×3=24, etc. For example, 2, 3, 3 and 7 can form (7+3-2)×3=24 and so on. Practice has proved that this method has the highest utilization rate and hit rate.

2. Use the operational characteristics of 0, 1 1 to solve it.

For example, 3, 4, 4 and 8 can form 3×8+4-4=24. For another example, 4,5, j and k can form11× (5-4)+13 = 24 and so on.
