How to remember maths formulae?

Now i m in 12th. How should i study maths?

we donot require to remember any formula.

All you have to do is practice by writing. Practice the problems by writing again and again. Formula will be remembered its self if think why any steps your are doing.

That is take a question see the soln. next step. and think why that step is requird to solve. Ask any 1 if u have dout in any step. Now write the soln without watching book. and see where u made mistake. If you work more number of problem more time u will be best.
lets see a simple example.
(5+2)+3*4/2
=7+3*4/2
=7+3*2
=7+6
=13
In this sum why i solvd braces 1st because its rule BODMAS
that is braces first then off then division multiply add then substract.

so third 2nd step i did division becoz after braces it should be solved thats the rule.
here you dnt have to remember BODMAS formula if you keep solving 50 questions repeatdly. than it will be your habit and you know the reason too that why that is solvd so. you know the concept.so you can solve
(5-2)*5*9*(3+5)
you an solve any sample of problem. If you understand. Like in exam some time they are difrent ques.
so, there are two thing
practice to solve any problem frequently without any query.

Understanding concept.so that you can solve any new question or chalange to similiar topic.

Keep practising. The more time you invest the more you will remember.

use of formula frequently sets it easily in memory.

our world is simple,we use numbers everyday.
but is easy when we have formulas,but is better when we use the simple logic,what we want to get and the result is,the result of our simple logic.

This is like asking us how to use your brain. It's YOUR brain, so YOU use it!
