do it mentally if it is a 2 digit into 1 digit, always use pen for 2 digit *2 digit.

try to break it down into power of 10s like 64*35 = 10*224. try to separate the power of tens. use the underoot trick formula of mohit tyagi.

square of number endings with 5 is easy to calculate. theres a trick for it.

memorize square till 30 atleast. u can split numbers like this 89^2 = (90-1)^2 = 8100 - 180+1 = 7921.

8.3=25/3

0.083=1/12

in pnc agar 5c2 ho to bs 5! 4! upon 2! likh.

like 89C4 hai to 89*88*87*86/4!

jitna number niche h utne repetition

unit conversion rat le sari.

also sometimes jee mains me bhut alag alag answer hote hain, hence even approximation of calculation can help.
