Let's roll up our sleeves and solve this. We have 776 and we're going to multiply it by 7, essentially adding 776 to itself 7 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

So, 776*7 = 5432
