Sure thing! We've got 907 and we're gonna multiply it by 11. That's the same as adding 907 to itself 11 times.
Step 1: 0 + 907 = 907
Step 2: 907 + 907 = 1814
Step 3: 1814 + 907 = 2721
Step 4: 2721 + 907 = 3628
Step 5: 3628 + 907 = 4535
Step 6: 4535 + 907 = 5442
Step 7: 5442 + 907 = 6349
Step 8: 6349 + 907 = 7256
Step 9: 7256 + 907 = 8163
Step 10: 8163 + 907 = 9070
Step 11: 9070 + 907 = 9977

So, 907*11 = 9977
