This channel is dedicated to presenting challenging math, and physics problems and solving them. The emphasis is on teaching problem solving methods, not just presenting a solution. I solve the problems step by step and try to teach how to approach a problem. In addition to these subjects, I will post occasional recite of famous Persian poetries. The channel is organized into playlists. Here is how to decipher the playlist names: 1. First section For ex. Algebra Problems, solving inequalities: teaches how to solve inequalities. Algebra Practice Problems are practice problems based on the thought concepts. 2. Two or three words after the first word: explains the category of problems (Inequalities, equations, ...) If you are interested and you like me to continue posting interesting problems, please consider subscribing to the channel and leaving feedback or giving problems thumbs up/down.
