Let's get this math done. We have 301 and we're going to multiply it by 10. This is the same as taking 301 and adding it to itself 10 times.
Step 1: 0 + 301 = 301
Step 2: 301 + 301 = 602
Step 3: 602 + 301 = 903
Step 4: 903 + 301 = 1204
Step 5: 1204 + 301 = 1505
Step 6: 1505 + 301 = 1806
Step 7: 1806 + 301 = 2107
Step 8: 2107 + 301 = 2408
Step 9: 2408 + 301 = 2709
Step 10: 2709 + 301 = 3010

So, 301*10 = 3010
