OK, let's crack this. We're given 323 and our task is to multiply it by 7. Essentially, we'll be adding 323 to itself 7 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

So, 323*7 = 2261
