OK, let's crack this. We're given 277 and our task is to multiply it by 7. Essentially, we'll be adding 277 to itself 7 times.
Step 1: 0 + 277 = 277
Step 2: 277 + 277 = 554
Step 3: 554 + 277 = 831
Step 4: 831 + 277 = 1108
Step 5: 1108 + 277 = 1385
Step 6: 1385 + 277 = 1662
Step 7: 1662 + 277 = 1939

So, 277*7 = 1939
