**What is an Algebraic Expression: **

An algebraic expression is a collection of terms separated by plus (+) or minus (–) sign. For example : 3x + 5y, 7y – 2x, 2x – ay + az, etc.

**What is Terms: **

The various parts of an algebraic expression that are separated by ‘+’ or ‘–’ sign are called terms.

**For example :**** Algebraic expression No. of Terms terms**

–32x 1 –32x

2x + 3y 2 2x and 3y

ax – 5y + cz 3 ax, –5y and cz

**Types of Algebraic Expressions :**

(i) **Monomial** : An algebraic expression having only one term is called a monomial. For ex. 8y, –7xy, 4x^{2}, abx, etc.

The term ‘**mono’** means ‘one’ (1).

(ii) **Binomial** : An algebraic expression having two terms is called a binomial. For ex. 8x + 3y, 8x + 3, 8 + 3y, a + bz, 9 – 4y, 2x^{2} – 4z, 6y^{2} – 5y, etc.

‘ bi’ means ‘two’.

(iii) **Trinomial** : An algebraic expression having three terms is called a trinomial. For ex. ax – 5y + 8z, 3x^{2} + 4x + 7, 9y^{2} – 3y + 2x, etc.

‘tri means ‘three’.

(iv) **Multinomial** : An algebraic expression having two or more terms is called a multinomial.
