Let's get this math done. We have 602 and we're going to multiply it by 9. This is the same as taking 602 and adding it to itself 9 times.
Step 1: 0 + 602 = 602
Step 2: 602 + 602 = 1204
Step 3: 1204 + 602 = 1806
Step 4: 1806 + 602 = 2408
Step 5: 2408 + 602 = 3010
Step 6: 3010 + 602 = 3612
Step 7: 3612 + 602 = 4214
Step 8: 4214 + 602 = 4816
Step 9: 4816 + 602 = 5418

So, 602*9 = 5418
