Why some people can solve math problems easily while others cannot?
It depends on way of understanding and approaching.
Understanding means,
first we know the details of the questions ( without understanding can’t solve math problem).
Second
approaching,
for example, the question is about cubic problem but we understand that deals with some other problem that is the reason most of them are get trouble with maths.
the people who solve math easily they are familiar to understand and approaching techniques leads to Math genius. nothing more than that.
One cannot solve mathematics problem just by looking at the question rather one has to be strong in the base of that subject or you can call the foundation of that. You have to clear that base by practising a lot of variety of questions so you will get an insight into the various problems that are present and it will provide confidence too. so One has to practice a lot to become perfect.
