Let's roll up our sleeves and solve this. We have 752 and we're going to multiply it by 24, essentially adding 752 to itself 24 times.
Step 1: 0 + 752 = 752
Step 2: 752 + 752 = 1504
Step 3: 1504 + 752 = 2256
Step 4: 2256 + 752 = 3008
Step 5: 3008 + 752 = 3760
Step 6: 3760 + 752 = 4512
Step 7: 4512 + 752 = 5264
Step 8: 5264 + 752 = 6016
Step 9: 6016 + 752 = 6768
Step 10: 6768 + 752 = 7520
Step 11: 7520 + 752 = 8272
Step 12: 8272 + 752 = 9024
Step 13: 9024 + 752 = 9776
Step 14: 9776 + 752 = 10528
Step 15: 10528 + 752 = 11280
Step 16: 11280 + 752 = 12032
Step 17: 12032 + 752 = 12784
Step 18: 12784 + 752 = 13536
Step 19: 13536 + 752 = 14288
Step 20: 14288 + 752 = 15040
Step 21: 15040 + 752 = 15792
Step 22: 15792 + 752 = 16544
Step 23: 16544 + 752 = 17296
Step 24: 17296 + 752 = 18048

So, 752*24 = 18048
