OK, let's crack this. We're given 773 and our task is to multiply it by 10. Essentially, we'll be adding 773 to itself 10 times.
Step 1: 0 + 773 = 773
Step 2: 773 + 773 = 1546
Step 3: 1546 + 773 = 2319
Step 4: 2319 + 773 = 3092
Step 5: 3092 + 773 = 3865
Step 6: 3865 + 773 = 4638
Step 7: 4638 + 773 = 5411
Step 8: 5411 + 773 = 6184
Step 9: 6184 + 773 = 6957
Step 10: 6957 + 773 = 7730

So, 773*10 = 7730
