Let's get this math done. We have 223 and we're going to multiply it by 9. This is the same as taking 223 and adding it to itself 9 times.
Step 1: 0 + 223 = 223
Step 2: 223 + 223 = 446
Step 3: 446 + 223 = 669
Step 4: 669 + 223 = 892
Step 5: 892 + 223 = 1115
Step 6: 1115 + 223 = 1338
Step 7: 1338 + 223 = 1561
Step 8: 1561 + 223 = 1784
Step 9: 1784 + 223 = 2007

So, 223*9 = 2007
