Alright, let's solve this math problem step by step. First, we have the number 662. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 18. So, we're going to take the number 662 and add it to itself 18 times.
Step 1: 0 + 662 = 662
Step 2: 662 + 662 = 1324
Step 3: 1324 + 662 = 1986
Step 4: 1986 + 662 = 2648
Step 5: 2648 + 662 = 3310
Step 6: 3310 + 662 = 3972
Step 7: 3972 + 662 = 4634
Step 8: 4634 + 662 = 5296
Step 9: 5296 + 662 = 5958
Step 10: 5958 + 662 = 6620
Step 11: 6620 + 662 = 7282
Step 12: 7282 + 662 = 7944
Step 13: 7944 + 662 = 8606
Step 14: 8606 + 662 = 9268
Step 15: 9268 + 662 = 9930
Step 16: 9930 + 662 = 10592
Step 17: 10592 + 662 = 11254
Step 18: 11254 + 662 = 11916

So, 662*18 = 11916
