Sure thing! We've got 323 and we're gonna multiply it by 9. That's the same as adding 323 to itself 9 times.
Step 1: 0 + 323 = 323
Step 2: 323 + 323 = 646
Step 3: 646 + 323 = 969
Step 4: 969 + 323 = 1292
Step 5: 1292 + 323 = 1615
Step 6: 1615 + 323 = 1938
Step 7: 1938 + 323 = 2261
Step 8: 2261 + 323 = 2584
Step 9: 2584 + 323 = 2907

So, 323*9 = 2907
