Without delay, let's solve this. We've got 86 and we will be multiplying it by 10, that is, adding 86 to itself 10 times.
Step 1: 0 + 86 = 86
Step 2: 86 + 86 = 172
Step 3: 172 + 86 = 258
Step 4: 258 + 86 = 344
Step 5: 344 + 86 = 430
Step 6: 430 + 86 = 516
Step 7: 516 + 86 = 602
Step 8: 602 + 86 = 688
Step 9: 688 + 86 = 774
Step 10: 774 + 86 = 860

So, 86*10 = 860
