Without delay, let's solve this. We've got 917 and we will be multiplying it by 7, that is, adding 917 to itself 7 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

So, 917*7 = 6419
