learning could be fun

it's not enough to learn one concept 

to figure out an unknown concept 

it's probably necessary to learn a lot of concepts 

to figure out an unknown concept 

during a math education, a student could learn different mathematical concepts and after education 

then maybe that student could figure out an unknown concept 

during a political science education, a student could learn different political concepts 

and after education 

then maybe that student could figure out an unknown concept 

and so on
