Hello,

There is no practical in maths subject. They are hard problems and have some ways to solve it but the answer at the end is one.

You can't change  the output and say it is also a solution which is completely wrong. For this there is no practical. Maths is all about practice. Maths becomes friendly to those persons who practice them rigorously along with understanding the concepts.

Only papers like physics,chemistry and biology have practical labs.

Hope it helps!
