Sure thing, let's get straight to it. We start with 682 and we're going to multiply it by 18, which means adding 682 to itself 18 times.
Step 1: 0 + 682 = 682
Step 2: 682 + 682 = 1364
Step 3: 1364 + 682 = 2046
Step 4: 2046 + 682 = 2728
Step 5: 2728 + 682 = 3410
Step 6: 3410 + 682 = 4092
Step 7: 4092 + 682 = 4774
Step 8: 4774 + 682 = 5456
Step 9: 5456 + 682 = 6138
Step 10: 6138 + 682 = 6820
Step 11: 6820 + 682 = 7502
Step 12: 7502 + 682 = 8184
Step 13: 8184 + 682 = 8866
Step 14: 8866 + 682 = 9548
Step 15: 9548 + 682 = 10230
Step 16: 10230 + 682 = 10912
Step 17: 10912 + 682 = 11594
Step 18: 11594 + 682 = 12276

So, 682*18 = 12276
