*Addition and Subtraction of Surds
*Multiplication of Surds. i.Multiplication of Surds having same Order ii. Multiplication of Surds having different Order
*Rationalising Factor of a Surd
*Simplifying a surd by Rationalizing denominator of a surd

==Concept 1: '''Definition of surds'''==
Irrational root of rational number. Example:<math>\sqrt{2}, 7\sqrt{5}, \sqrt{x}</math>

===Learning objectives===
#know the meaning of surds
#recognising radicand and order of surds

===Notes for teachers===
If you can't simplify a number to remove a square root (or cube root etc) then it is a surd.
If it is a root and irrational, it is a surd.
But not all roots are surds.

==Concept-2: '''Like and Unlike surds'''==
===Learning objectives===
#Know the meaning of surd
#recognising the meaning of order and radicand
#Examples of like and unlike surds
#To change surd to simplest form
#Addition and Multiplication og surds

===Notes for teachers===
1.Like surds: A group of surds having same order and same radicand in their simplest form.
Example: <math>3\sqrt{5}, 7\sqrt{5}, x\sqrt{5}</math> 
2.Unlike surds: Groups of surds having different orders or different radicandsor both in their simplest form.
Example: <math>\sqrt{a}, 3\sqrt{2}, x\sqrt{5}</math> 
3.Addition and sustraction of surds.
Example: <math>2\sqrt{5}+3\sqrt{5}-\sqrt{5}</math> 
4.Multiplication of surds.
Example: <math>7\sqrt{3} X 2\sqrt{5}</math>
