### In the lessons

In everyday life «press hash» on the phone means press #; #hashtags label posts online. In computing lessons, a hash turns a password into a scrambled code. In cooking, hash and hash browns (fried grated potato) are breakfast foods. In stories «made a hash of it» is a funny way to say «messed it up». Safety: drugs are illegal and harmful. Phrases: hash browns, make a hash of, hash out, hashtag.
