Solve Physics and Math Problems at

I have shared quite a lot of sites in this blog about places where you can find challenging math problems for your intellectual satisfaction. In this post, I am going to introduce a website called, a problem solving website which provides different levels of physics, computer science, and math problems depending on solver’s ability.

Brilliant Physics and Math Problems provides different levels of physics and math problems, from practice to Olympiad level. Recently, it has also added problems in computer science particularly on data structures and algorithm. Math problems include challenges in algebra, number theory, geometry, and combinatorics. Physics problems include challenges in mechanics, electricity and magnetism.

Just like in other challenges and games, problem solved at have corresponding points. Players can exchange points for corresponding prizes. Players can also discuss problems within the website.

2250 Interactive K-12 Mathematics Problems with Solutions

One great website I discovered recently is A+ Click Math and Logic Problems. The website contains 2250 interactive mathematics problems from Kindergarten to Grade 12. Each problem has clickable choices and a solution appears if user’s answer is incorrect.

(c) A+Click

An image from a sample problem in A+Click is shown above. The question asks for the shortest path among A, B, C, and D from the origin to (7,6).

According to the website, A+Click’s  database adapts to student ability. To progress to a higher level, the student must answer 5 consecutive problems correctly.

If you want to see more challenging problems, Mathematics and Multimedia contains links to more than 20,000 mathematics contest problems and solutions.
