Let's get this math done. We have 453 and we're going to multiply it by 6. This is the same as taking 453 and adding it to itself 6 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

So, 453*6 = 2718
