Let's roll up our sleeves and solve this. We have 584 and we're going to multiply it by 24, essentially adding 584 to itself 24 times.
Step 1: 0 + 584 = 584
Step 2: 584 + 584 = 1168
Step 3: 1168 + 584 = 1752
Step 4: 1752 + 584 = 2336
Step 5: 2336 + 584 = 2920
Step 6: 2920 + 584 = 3504
Step 7: 3504 + 584 = 4088
Step 8: 4088 + 584 = 4672
Step 9: 4672 + 584 = 5256
Step 10: 5256 + 584 = 5840
Step 11: 5840 + 584 = 6424
Step 12: 6424 + 584 = 7008
Step 13: 7008 + 584 = 7592
Step 14: 7592 + 584 = 8176
Step 15: 8176 + 584 = 8760
Step 16: 8760 + 584 = 9344
Step 17: 9344 + 584 = 9928
Step 18: 9928 + 584 = 10512
Step 19: 10512 + 584 = 11096
Step 20: 11096 + 584 = 11680
Step 21: 11680 + 584 = 12264
Step 22: 12264 + 584 = 12848
Step 23: 12848 + 584 = 13432
Step 24: 13432 + 584 = 14016

So, 584*24 = 14016
