Let's get this math done. We have 236 and we're going to multiply it by 9. This is the same as taking 236 and adding it to itself 9 times.
Step 1: 0 + 236 = 236
Step 2: 236 + 236 = 472
Step 3: 472 + 236 = 708
Step 4: 708 + 236 = 944
Step 5: 944 + 236 = 1180
Step 6: 1180 + 236 = 1416
Step 7: 1416 + 236 = 1652
Step 8: 1652 + 236 = 1888
Step 9: 1888 + 236 = 2124

So, 236*9 = 2124
