OK, let's crack this. We're given 856 and our task is to multiply it by 9. Essentially, we'll be adding 856 to itself 9 times.
Step 1: 0 + 856 = 856
Step 2: 856 + 856 = 1712
Step 3: 1712 + 856 = 2568
Step 4: 2568 + 856 = 3424
Step 5: 3424 + 856 = 4280
Step 6: 4280 + 856 = 5136
Step 7: 5136 + 856 = 5992
Step 8: 5992 + 856 = 6848
Step 9: 6848 + 856 = 7704

So, 856*9 = 7704
