Let's roll up our sleeves and solve this. We have 754 and we're going to multiply it by 18, essentially adding 754 to itself 18 times.
Step 1: 0 + 754 = 754
Step 2: 754 + 754 = 1508
Step 3: 1508 + 754 = 2262
Step 4: 2262 + 754 = 3016
Step 5: 3016 + 754 = 3770
Step 6: 3770 + 754 = 4524
Step 7: 4524 + 754 = 5278
Step 8: 5278 + 754 = 6032
Step 9: 6032 + 754 = 6786
Step 10: 6786 + 754 = 7540
Step 11: 7540 + 754 = 8294
Step 12: 8294 + 754 = 9048
Step 13: 9048 + 754 = 9802
Step 14: 9802 + 754 = 10556
Step 15: 10556 + 754 = 11310
Step 16: 11310 + 754 = 12064
Step 17: 12064 + 754 = 12818
Step 18: 12818 + 754 = 13572

So, 754*18 = 13572
