Without delay, let's solve this. We've got 425 and we will be multiplying it by 10, that is, adding 425 to itself 10 times.
Step 1: 0 + 425 = 425
Step 2: 425 + 425 = 850
Step 3: 850 + 425 = 1275
Step 4: 1275 + 425 = 1700
Step 5: 1700 + 425 = 2125
Step 6: 2125 + 425 = 2550
Step 7: 2550 + 425 = 2975
Step 8: 2975 + 425 = 3400
Step 9: 3400 + 425 = 3825
Step 10: 3825 + 425 = 4250

So, 425*10 = 4250
