OK, let's work through this together. We're starting with 833 and we're going to multiply it by 9, which means we add 833 to itself 9 times.
Step 1: 0 + 833 = 833
Step 2: 833 + 833 = 1666
Step 3: 1666 + 833 = 2499
Step 4: 2499 + 833 = 3332
Step 5: 3332 + 833 = 4165
Step 6: 4165 + 833 = 4998
Step 7: 4998 + 833 = 5831
Step 8: 5831 + 833 = 6664
Step 9: 6664 + 833 = 7497

So, 833*9 = 7497
