Alright, let's solve this math problem step by step. First, we have the number 917. 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 917 and add it to itself 18 times.
Step 1: 0 + 917 = 917
Step 2: 917 + 917 = 1834
Step 3: 1834 + 917 = 2751
Step 4: 2751 + 917 = 3668
Step 5: 3668 + 917 = 4585
Step 6: 4585 + 917 = 5502
Step 7: 5502 + 917 = 6419
Step 8: 6419 + 917 = 7336
Step 9: 7336 + 917 = 8253
Step 10: 8253 + 917 = 9170
Step 11: 9170 + 917 = 10087
Step 12: 10087 + 917 = 11004
Step 13: 11004 + 917 = 11921
Step 14: 11921 + 917 = 12838
Step 15: 12838 + 917 = 13755
Step 16: 13755 + 917 = 14672
Step 17: 14672 + 917 = 15589
Step 18: 15589 + 917 = 16506

So, 917*18 = 16506
