Without delay, let's solve this. We've got 764 and we will be multiplying it by 24, that is, adding 764 to itself 24 times.
Step 1: 0 + 764 = 764
Step 2: 764 + 764 = 1528
Step 3: 1528 + 764 = 2292
Step 4: 2292 + 764 = 3056
Step 5: 3056 + 764 = 3820
Step 6: 3820 + 764 = 4584
Step 7: 4584 + 764 = 5348
Step 8: 5348 + 764 = 6112
Step 9: 6112 + 764 = 6876
Step 10: 6876 + 764 = 7640
Step 11: 7640 + 764 = 8404
Step 12: 8404 + 764 = 9168
Step 13: 9168 + 764 = 9932
Step 14: 9932 + 764 = 10696
Step 15: 10696 + 764 = 11460
Step 16: 11460 + 764 = 12224
Step 17: 12224 + 764 = 12988
Step 18: 12988 + 764 = 13752
Step 19: 13752 + 764 = 14516
Step 20: 14516 + 764 = 15280
Step 21: 15280 + 764 = 16044
Step 22: 16044 + 764 = 16808
Step 23: 16808 + 764 = 17572
Step 24: 17572 + 764 = 18336

So, 764*24 = 18336
