Let's get this math done. We have 329 and we're going to multiply it by 7. This is the same as taking 329 and adding it to itself 7 times.
Step 1: 0 + 329 = 329
Step 2: 329 + 329 = 658
Step 3: 658 + 329 = 987
Step 4: 987 + 329 = 1316
Step 5: 1316 + 329 = 1645
Step 6: 1645 + 329 = 1974
Step 7: 1974 + 329 = 2303

So, 329*7 = 2303
