Without delay, let's solve this. We've got 475 and we will be multiplying it by 15, that is, adding 475 to itself 15 times.
Step 1: 0 + 475 = 475
Step 2: 475 + 475 = 950
Step 3: 950 + 475 = 1425
Step 4: 1425 + 475 = 1900
Step 5: 1900 + 475 = 2375
Step 6: 2375 + 475 = 2850
Step 7: 2850 + 475 = 3325
Step 8: 3325 + 475 = 3800
Step 9: 3800 + 475 = 4275
Step 10: 4275 + 475 = 4750
Step 11: 4750 + 475 = 5225
Step 12: 5225 + 475 = 5700
Step 13: 5700 + 475 = 6175
Step 14: 6175 + 475 = 6650
Step 15: 6650 + 475 = 7125

So, 475*15 = 7125
