Without delay, let's solve this. We've got 458 and we will be multiplying it by 10, that is, adding 458 to itself 10 times.
Step 1: 0 + 458 = 458
Step 2: 458 + 458 = 916
Step 3: 916 + 458 = 1374
Step 4: 1374 + 458 = 1832
Step 5: 1832 + 458 = 2290
Step 6: 2290 + 458 = 2748
Step 7: 2748 + 458 = 3206
Step 8: 3206 + 458 = 3664
Step 9: 3664 + 458 = 4122
Step 10: 4122 + 458 = 4580

So, 458*10 = 4580
