শতকরা (Percentage) টপিকের বিষয়বস্তুঃ

গণিত (Mathematics) হলো সংখ্যা, পরিমাণ, আকার, গঠন এবং এদের মধ্যাকার সম্পর্ক ও পরিবর্তন সংক্রান্ত একটি মৌলিক বিজ্ঞান, যা যুক্তি ও বিশ্লেষণের মাধ্যমে সমস্যার সমাধান করে । এটি মূলত গণনা ও পরিমাপের বিদ্যা, যাকে অনেক সময় "বিজ্ঞানের ভাষা" বা "বিশ্বের ভাষা" বলা হয় । গণিতের প্রধান শাখাগুলোর মধ্যে রয়েছে পাটিগণিত, বীজগণিত, জ্যামিতি, ত্রিকোণমিতি, ক্যালকুলাস এবং পরিসংখ্যান।

গণিতের মূল বিষয়বস্তু ও ধারণা:

সংখ্যা (Number): গণনার মূল ভিত্তি।
বীজগণিত (Algebra): প্রতীক ও চলক ব্যবহার করে গাণিতিক সম্পর্কের সাধারণ রূপায়ণ ।
জ্যামিতি (Geometry): আকার, আকৃতি এবং স্থানের (space) বৈশিষ্ট্য সংক্রান্ত আলোচনা ।
বিশ্লেষণ (Analysis): পরিবর্তন ও পরিমাণের ধ্রুবক বা চলক মান নিয়ে কাজ করা।ধাঁধা ও যুক্তি:
যৌক্তিক চিন্তাধারা বিকাশে গণিত অপরিহার্য ।
