In Algebra, **Pronumerals** stand for numbers and follow the same rules as numbers in mathematical operations.

**Terms:**

Terms may have one or more Pronumerals (Variables ), can be just a number ( Constant ), or a product of number and Pronumerals where the number is called a **Coefficient**.

Example : * 7x, 13b, 3ab, 9xy, 2*

**Expressions:**

Expressions are made by adding or subtracting 2 or more Terms.

Example: * 3a + 5b + 7c , 4xy – z , 7q + 2, 8( t – 6)*

**Equations:**

Equations have Equal signs that connect Terms and Expressions.

Example: *c = 3a + 5b , u = 4xy – z , s = 6t , r = 8 ( t – 6 )*
