OK, let's crack this. We're given 527 and our task is to multiply it by 24. Essentially, we'll be adding 527 to itself 24 times.
Step 1: 0 + 527 = 527
Step 2: 527 + 527 = 1054
Step 3: 1054 + 527 = 1581
Step 4: 1581 + 527 = 2108
Step 5: 2108 + 527 = 2635
Step 6: 2635 + 527 = 3162
Step 7: 3162 + 527 = 3689
Step 8: 3689 + 527 = 4216
Step 9: 4216 + 527 = 4743
Step 10: 4743 + 527 = 5270
Step 11: 5270 + 527 = 5797
Step 12: 5797 + 527 = 6324
Step 13: 6324 + 527 = 6851
Step 14: 6851 + 527 = 7378
Step 15: 7378 + 527 = 7905
Step 16: 7905 + 527 = 8432
Step 17: 8432 + 527 = 8959
Step 18: 8959 + 527 = 9486
Step 19: 9486 + 527 = 10013
Step 20: 10013 + 527 = 10540
Step 21: 10540 + 527 = 11067
Step 22: 11067 + 527 = 11594
Step 23: 11594 + 527 = 12121
Step 24: 12121 + 527 = 12648

So, 527*24 = 12648
