OK, let's work through this together. We're starting with 776 and we're going to multiply it by 11, which means we add 776 to itself 11 times.
Step 1: 0 + 776 = 776
Step 2: 776 + 776 = 1552
Step 3: 1552 + 776 = 2328
Step 4: 2328 + 776 = 3104
Step 5: 3104 + 776 = 3880
Step 6: 3880 + 776 = 4656
Step 7: 4656 + 776 = 5432
Step 8: 5432 + 776 = 6208
Step 9: 6208 + 776 = 6984
Step 10: 6984 + 776 = 7760
Step 11: 7760 + 776 = 8536

So, 776*11 = 8536
