Let's get this math done. We have 242 and we're going to multiply it by 9. This is the same as taking 242 and adding it to itself 9 times.
Step 1: 0 + 242 = 242
Step 2: 242 + 242 = 484
Step 3: 484 + 242 = 726
Step 4: 726 + 242 = 968
Step 5: 968 + 242 = 1210
Step 6: 1210 + 242 = 1452
Step 7: 1452 + 242 = 1694
Step 8: 1694 + 242 = 1936
Step 9: 1936 + 242 = 2178

So, 242*9 = 2178
