Let's roll up our sleeves and solve this. We have 746 and we're going to multiply it by 18, essentially adding 746 to itself 18 times.
Step 1: 0 + 746 = 746
Step 2: 746 + 746 = 1492
Step 3: 1492 + 746 = 2238
Step 4: 2238 + 746 = 2984
Step 5: 2984 + 746 = 3730
Step 6: 3730 + 746 = 4476
Step 7: 4476 + 746 = 5222
Step 8: 5222 + 746 = 5968
Step 9: 5968 + 746 = 6714
Step 10: 6714 + 746 = 7460
Step 11: 7460 + 746 = 8206
Step 12: 8206 + 746 = 8952
Step 13: 8952 + 746 = 9698
Step 14: 9698 + 746 = 10444
Step 15: 10444 + 746 = 11190
Step 16: 11190 + 746 = 11936
Step 17: 11936 + 746 = 12682
Step 18: 12682 + 746 = 13428

So, 746*18 = 13428
