Without delay, let's solve this. We've got 453 and we will be multiplying it by 24, that is, adding 453 to itself 24 times.
Step 1: 0 + 453 = 453
Step 2: 453 + 453 = 906
Step 3: 906 + 453 = 1359
Step 4: 1359 + 453 = 1812
Step 5: 1812 + 453 = 2265
Step 6: 2265 + 453 = 2718
Step 7: 2718 + 453 = 3171
Step 8: 3171 + 453 = 3624
Step 9: 3624 + 453 = 4077
Step 10: 4077 + 453 = 4530
Step 11: 4530 + 453 = 4983
Step 12: 4983 + 453 = 5436
Step 13: 5436 + 453 = 5889
Step 14: 5889 + 453 = 6342
Step 15: 6342 + 453 = 6795
Step 16: 6795 + 453 = 7248
Step 17: 7248 + 453 = 7701
Step 18: 7701 + 453 = 8154
Step 19: 8154 + 453 = 8607
Step 20: 8607 + 453 = 9060
Step 21: 9060 + 453 = 9513
Step 22: 9513 + 453 = 9966
Step 23: 9966 + 453 = 10419
Step 24: 10419 + 453 = 10872

So, 453*24 = 10872
