OK, let's work through this together. We're starting with 959 and we're going to multiply it by 9, which means we add 959 to itself 9 times.
Step 1: 0 + 959 = 959
Step 2: 959 + 959 = 1918
Step 3: 1918 + 959 = 2877
Step 4: 2877 + 959 = 3836
Step 5: 3836 + 959 = 4795
Step 6: 4795 + 959 = 5754
Step 7: 5754 + 959 = 6713
Step 8: 6713 + 959 = 7672
Step 9: 7672 + 959 = 8631

So, 959*9 = 8631
