Let's get this math done. We have 862 and we're going to multiply it by 10. This is the same as taking 862 and adding it to itself 10 times.
Step 1: 0 + 862 = 862
Step 2: 862 + 862 = 1724
Step 3: 1724 + 862 = 2586
Step 4: 2586 + 862 = 3448
Step 5: 3448 + 862 = 4310
Step 6: 4310 + 862 = 5172
Step 7: 5172 + 862 = 6034
Step 8: 6034 + 862 = 6896
Step 9: 6896 + 862 = 7758
Step 10: 7758 + 862 = 8620

So, 862*10 = 8620
