ADDITION OF ALGEBRAIC LIKE & UNLIKE TERM

**Addition of Like Term**

**The sum of two or more like terms is another like term, the
coefficient of which is the sum of the coefficient of the like terms.**

**Example –**

**1) 7x + 4x -9x = 11 x
– 9x =
2x**

**2) 10xy + 12xy –
8yx =
22xy – 8xy = 14xy**

**3) 25ab – 15ab +
5ba =
30ab – 15ab = 15ab**

**4) 9x² - 8x² + 10x²
= 19x² - 8x² = 11x²**

**5) 15y⁴x² + 10x²y⁴ +
15x²y⁴ =
40 x²y⁴**

**Addition of Unlike Term –**

**Unlike terms cannot be added, we will write them along with
their signs to form an algebraic expression.**

**Example –**

**1) the sum of -5a and 7b is to be written as -5a + 7b**

**2) the sum of -10x, 4y and 9z is to be written as -10x + 4y
+ 9z**
