Do not use the computer, which using the limits of his brain and slows the learning of mathematics easy way, the combination formula.
24 * 23 * 22 * 21 * 20 / (5 * 4 * 3 * 2) = 42,504
5 * 4 disposes of 20
3 reduced 21.7
2 reduces 24 to 12
then you have 12 * 23 * 22 * 7
easy way to do this is (10 * 23 + 46) = 276
now 20 * 276 + 2 * 276 = 6072 and eventually you can do 6072 * 7 = 42504
I hope that helps
