Let's get this math done. We have 297 and we're going to multiply it by 9. This is the same as taking 297 and adding it to itself 9 times.
Step 1: 0 + 297 = 297
Step 2: 297 + 297 = 594
Step 3: 594 + 297 = 891
Step 4: 891 + 297 = 1188
Step 5: 1188 + 297 = 1485
Step 6: 1485 + 297 = 1782
Step 7: 1782 + 297 = 2079
Step 8: 2079 + 297 = 2376
Step 9: 2376 + 297 = 2673

So, 297*9 = 2673
