Without delay, let's solve this. We've got 702 and we will be multiplying it by 10, that is, adding 702 to itself 10 times.
Step 1: 0 + 702 = 702
Step 2: 702 + 702 = 1404
Step 3: 1404 + 702 = 2106
Step 4: 2106 + 702 = 2808
Step 5: 2808 + 702 = 3510
Step 6: 3510 + 702 = 4212
Step 7: 4212 + 702 = 4914
Step 8: 4914 + 702 = 5616
Step 9: 5616 + 702 = 6318
Step 10: 6318 + 702 = 7020

So, 702*10 = 7020
