Addition and Subtraction of surds

- In addition and subtraction of surds we will learn how to find the sum or difference of two or more surds only when they are in the simplest form of like surds.
For addition and subtraction of surds, we have to check the surds that if they are similar surds or dissimilar #surds
Follow the following steps to find the addition and subtraction of two or more surds:
Step I: Convert each surd in its simplest mixed form.
Step II: Then find the sum or difference of rational co-efficient of like surds.
Step III: Finally, to get the required sum or difference of like surds multiply the result obtained in step II by the surd-factor of like surds.
Step IV: The sum or difference of unlike surds is expressed in a number of terms by connecting them with positive sign (+) or negative (-) sign.
If the surds are similar, then we can sum or subtract rational coefficients to find out the result of addition or subtraction.

Sorry for ignoring 1 as pert of perfect square numbers 🙏
Though it's negligible in surd
May God bless you
🙏🙏🙏
Sir I am still lost in the first example
so you are saying 2 root 2 + 3 root 2 - square root of 2 is 4 root 2
Nice
