An algorithm is a set of steps to solve a problem or produce a specific outcome.

For example, here's a simple algorithm to make ice cubes:

1. Take out an ice cube tray
2. Pour water into the ice cube tray
3. Put the ice cube tray in freezer
4. Wait for 3 hours until the ice is set
5. Remove 2 ice cubes from the tray and place it in your cup

Algorithms often involve logic to solve more difficult problems or increase efficiency.

For example, an algorithm to help you decide what to wear based on the weather might use if/else statements like this:

1. If it is raining outside, wear a rain jacket and take an umbrella
2. Else if it is hot outside, wear a t-shirt, shorts, and slippers
3. Else if it is cool outside, wear a sweater and jeans
4. Else, wear a t-shirt and jeans

Or if you want to make ice cubes more efficiently, you could rewrite the ice cube making algorithm to use `if / else` statements and a `loop` like this:

1. Take out an ice cube tray
2. Pour water into the ice cube tray
3. Put the ice cube tray in freezer
4. Wait 1 hour and check on the ice cubes
5. If the ice is set, remove 2 ice cubes from the tray and place it in your cup
