As a senior You can adopt these three habits for Studying with enjoying ❤
1. Always remember "Nothing Comes for free" (Work Hard till Last breath) , Aur boards se Itna daro mat kabhi na kabhi to Dene hi hai , so chill..
2. BE "Consistent" .. 2 ghante hi padho but har roz regularly padho!
3. Syllabus completion ke sath sath Learning par Bohot FOCUS karna.
You will rock Bro!
One personal advice
Kabhi kabhi aisa lagega ki mehnat kar to rha/rhi hu but fir bhi Results nhi aa rhe yaa Parents dat de to It's Fine..!! Ek Kaan se sunu aur dusre se nikalo don't take tension and bus "TAKE IT AS A CHALLENGE" WORK even HARDER and prove yourself. ❤ All the Best😊

Mam,in exercise-4.2 sum 4 ,in your process you got -14.then how can we change it to+14 according to our question.because,we already got -14.why?

[@abemnara]

We reject the negative value because the question says two positive consecutive no. Not negative

Mam in the second question instead of taking out prime factors of 324 can't we do with the formula ?? If we do not consider the method in exercise
