Alright, let's solve this math problem step by step. First, we have the number 550. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 7. So, we're going to take the number 550 and add it to itself 7 times.
Step 1: 0 + 550 = 550
Step 2: 550 + 550 = 1100
Step 3: 1100 + 550 = 1650
Step 4: 1650 + 550 = 2200
Step 5: 2200 + 550 = 2750
Step 6: 2750 + 550 = 3300
Step 7: 3300 + 550 = 3850

So, 550*7 = 3850
