Let's roll up our sleeves and solve this. We have 453 and we're going to multiply it by 6, essentially adding 453 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
