Sure thing, let's get straight to it. We start with 852 and we're going to multiply it by 10, which means adding 852 to itself 10 times.
Step 1: 0 + 852 = 852
Step 2: 852 + 852 = 1704
Step 3: 1704 + 852 = 2556
Step 4: 2556 + 852 = 3408
Step 5: 3408 + 852 = 4260
Step 6: 4260 + 852 = 5112
Step 7: 5112 + 852 = 5964
Step 8: 5964 + 852 = 6816
Step 9: 6816 + 852 = 7668
Step 10: 7668 + 852 = 8520

So, 852*10 = 8520
