OK, let's work through this together. We're starting with 56 and we're going to multiply it by 18, which means we add 56 to itself 18 times.
Step 1: 0 + 56 = 56
Step 2: 56 + 56 = 112
Step 3: 112 + 56 = 168
Step 4: 168 + 56 = 224
Step 5: 224 + 56 = 280
Step 6: 280 + 56 = 336
Step 7: 336 + 56 = 392
Step 8: 392 + 56 = 448
Step 9: 448 + 56 = 504
Step 10: 504 + 56 = 560
Step 11: 560 + 56 = 616
Step 12: 616 + 56 = 672
Step 13: 672 + 56 = 728
Step 14: 728 + 56 = 784
Step 15: 784 + 56 = 840
Step 16: 840 + 56 = 896
Step 17: 896 + 56 = 952
Step 18: 952 + 56 = 1008

So, 56*18 = 1008
