Sure thing! We've got 686 and we're gonna multiply it by 11. That's the same as adding 686 to itself 11 times.
Step 1: 0 + 686 = 686
Step 2: 686 + 686 = 1372
Step 3: 1372 + 686 = 2058
Step 4: 2058 + 686 = 2744
Step 5: 2744 + 686 = 3430
Step 6: 3430 + 686 = 4116
Step 7: 4116 + 686 = 4802
Step 8: 4802 + 686 = 5488
Step 9: 5488 + 686 = 6174
Step 10: 6174 + 686 = 6860
Step 11: 6860 + 686 = 7546

So, 686*11 = 7546
