Sure thing, let's get straight to it. We start with 551 and we're going to multiply it by 7, which means adding 551 to itself 7 times.
Step 1: 0 + 551 = 551
Step 2: 551 + 551 = 1102
Step 3: 1102 + 551 = 1653
Step 4: 1653 + 551 = 2204
Step 5: 2204 + 551 = 2755
Step 6: 2755 + 551 = 3306
Step 7: 3306 + 551 = 3857

So, 551*7 = 3857
