The slide rule is used primarily for multiplication and division , and also for functions such as exponents , roots , logarithms and trigonometry , but typically not for addition or subtraction.

Cocktails: different types.
Juice, soda, cream, and alcoholic beverage of any kind are common components that are used to make perfect cocktail. This drink usually includes ice and flavoring ingredients as well. Plastic sticks or straws and fresh fruit are used to decorate the drink. Any cocktail should consist of three or more different ingredients otherwise it’s not a cocktail.
Exact origin of the drink is unsolved mystery. However its roots stretch back to the 19th century. Term “cocktail” was mentioned first in American magazine in 1806.
Non-alcoholic cocktail is called mocktail and sometimes punch. Word “mock” means mimic, imitate or copy. So mocktail imitates and looks like cocktail but it’s always alcohol-free. Fruit juices, iced tea, herbs, nectar, cream, and soft drinks are used to make mocktails.
Word “virgin” is often added to the front of mocktail name. For example Virgin Pina Colada doesn’t include rum but consists of the same ingredients as original drink.
Mocktails are great to serve party guests who prefer non-alcoholic drinks. These alcohol-free beverages are good choice for pregnant women, children, recovering alcoholics, and those who don’t like taste of alcohol and still want to enjoy fanciful cocktail.
They are also called beertails or shandies. This beer-based beverage may contain various soft drinks such as lemonade, fresh juices (lemon, orange, apple), sparkling water, and ginger ale. Beer cocktails may be light and sweet as well as heavy and rich.
