OK, let's crack this. We're given 7 and our task is to multiply it by 9. Essentially, we'll be adding 7 to itself 9 times.
Step 1: 0 + 7 = 7
Step 2: 7 + 7 = 14
Step 3: 14 + 7 = 21
Step 4: 21 + 7 = 28
Step 5: 28 + 7 = 35
Step 6: 35 + 7 = 42
Step 7: 42 + 7 = 49
Step 8: 49 + 7 = 56
Step 9: 56 + 7 = 63

So, 7*9 = 63
