Without delay, let's solve this. We've got 487 and we will be multiplying it by 10, that is, adding 487 to itself 10 times.
Step 1: 0 + 487 = 487
Step 2: 487 + 487 = 974
Step 3: 974 + 487 = 1461
Step 4: 1461 + 487 = 1948
Step 5: 1948 + 487 = 2435
Step 6: 2435 + 487 = 2922
Step 7: 2922 + 487 = 3409
Step 8: 3409 + 487 = 3896
Step 9: 3896 + 487 = 4383
Step 10: 4383 + 487 = 4870

So, 487*10 = 4870
