# Common set symbols with meaning and how to type them in Ms Word (with shortcut)

Set is a collection of different elements. It could be numbers, alphabets, etc. Various symbols are used to denote them (like ℝ denote set of Real Numbers) and their relationship and operation (subset, union, etc).

These set symbols helps to represent mathematical ideas in a concise way and saves space and time. In this blog we have listed all the commonly used **Set symbols** together and how to get them in Ms Word along with their keyboard shortcuts

## List of set symbols along with their meaning and how to get them in Ms Word

### Three methods to get symbols in Ms Word

**Insert Symbol Method:** Go to **Insert** > **Symbols **and select **More Symbols**. In the symbol window, click the desired symbol and hit insert. Following table gives the **subset **dropdown option of each symbol that can help you find a symbol.

**Math AutoCorrect:** This is the **smartest **way to get any symbol in Ms Word. **Simply type the Math AutoCorrect text and hit space to get symbol.** It works inside Equation editor. However, you can make it work outside equation editor, with following one time setting.

- Go to
**File > Options**to open Word Options - In
**Proofing**and select**AutoCorrect Options** - In
**Math Autocorrect**tab, check box against**“Use Math AutoCorrect rules outside of math regions”**

**Alt X Method**: Type the Alt X code of symbol and press Alt + X immediately after it to get symbol.

Let’s say, P = {1, 2, 3, 4} and Q = {1, 3, 5}
