Let's roll up our sleeves and solve this. We have 605 and we're going to multiply it by 10, essentially adding 605 to itself 10 times.
Step 1: 0 + 605 = 605
Step 2: 605 + 605 = 1210
Step 3: 1210 + 605 = 1815
Step 4: 1815 + 605 = 2420
Step 5: 2420 + 605 = 3025
Step 6: 3025 + 605 = 3630
Step 7: 3630 + 605 = 4235
Step 8: 4235 + 605 = 4840
Step 9: 4840 + 605 = 5445
Step 10: 5445 + 605 = 6050

So, 605*10 = 6050
