Let's roll up our sleeves and solve this. We have 479 and we're going to multiply it by 7, essentially adding 479 to itself 7 times.
Step 1: 0 + 479 = 479
Step 2: 479 + 479 = 958
Step 3: 958 + 479 = 1437
Step 4: 1437 + 479 = 1916
Step 5: 1916 + 479 = 2395
Step 6: 2395 + 479 = 2874
Step 7: 2874 + 479 = 3353

So, 479*7 = 3353
