If you have a database of 100 unsalted hashed passwords and a dictionary of 10,000 words you could hash the 10,000 words and compare each resulting hash to each

If you have a database of 100 unsalted hashed passwords and a dictionary of 10,000 words you could hash the 10,000 words and compare each resulting hash to each hash in the database. So that would take 10,000 hash operations. But if the passwords were individually salted you would have to individually hash each dictionary item for each hash in the database. So that would be 1,000,000 hash operations.
