Without delay, let's solve this. We've got 931 and we will be multiplying it by 8, that is, adding 931 to itself 8 times.
Step 1: 0 + 931 = 931
Step 2: 931 + 931 = 1862
Step 3: 1862 + 931 = 2793
Step 4: 2793 + 931 = 3724
Step 5: 3724 + 931 = 4655
Step 6: 4655 + 931 = 5586
Step 7: 5586 + 931 = 6517
Step 8: 6517 + 931 = 7448

So, 931*8 = 7448
