Question

How to remember cbse std 8 mathematics rational numbers formulae?

Answer 1

Write it in a paper and stick it in your home (somewhere you often cross) and then whenever you're crossing that place wait for 2 minutes and just read it with a concerted mind ( I say this cause many times while we are reading / doing someting we're thinking something even so we don't remember what actually we're doing / reading) . As a result you won't forget .
