in various secondary school mathematics national and international project competitions. Likewise, my students also got many elementary and secondary level mathematical
olympics achievements. In the recent past, my students got the first and the second place in the TÃœBÄ°TAK National Secondary School Research Projects Contest.
One of my students, **Read More** a team member of the national math team, received a bronze medal in IMO. I'm an author of many scientific articles about mathematics in the quarterly
magazine "Mathematical World". I'm the founder of **Matematik MeraklÄ±sÄ±**, which is a website dedicated to Mathematics. **Read Less**

It's a good way to practice maths and also the site encourages you to submit your answer with an
accompanying solution. Participants can not just simply guess the answer or predict what will be the answer based on the given, they need to know
and understand the topic. Also this refrains participants to just simply ask the answer from other people. So the method was excellent and
people will definitely learn many things about math.

I want to say my deepest gratitude in creating this website. The questions are not the typical
type and not normally taught to non-mathematical major degrees. I really hope that you'll continue your mission and vision in creating this site,
as this serves as a platform to enhance our mathematical skills. Hoping for the best good luck!!!

I see AhMath as the one encouraging self-paced learning or practice in solving math problems.
It does not put me into any kind of pressure like requiring myself to be the first one to solve the problems correctly and giving answers with a limited time.
Also, it gives me excitement for the next problems to solve as well as for the appearance of my name on the list of the people who submitted the correct
solutions and answers for those math problems. Overall, it gives me confidence to be better in math.

Thank you for everything, AhMath.

I knew AhMath from a facebook group, "Math Enthusiasts Quiz Group", that I just joined a few weeks ago.
Then I found that there are the "challenging math problems" here that refresh my Math skill.

I like many ideas on this website, the word "Math Enthusiasts" exactly
describes what I'm and it makes me recall the feeling about Math when I was young, it was fun and exciting!

I like the motto "Real than i, rational than n",
it's playing in my head and I'm still doubt about its meaning :-D

There is no time constraint for solving the problems so we can think about the solutions in the different ways. Sometimes the new solutions reveal the beauty of
Math and that only happens when we have time to think about other solutions.

Thank you the creator and moderator of this website, especially Ahmet Arduc,
who brings me back to the feeling of fun and exciting with his creative problems.

Ahmath is basically a great site. The problems are really challenging and mind boggling.
I really like the way that the Math enthusiasts should show the solution as well for each problem. You need to learn on your own.
This site greatly help me improve my Math skills and writing solutions as well. Thank you much Ahmath for an amazing job. More power and God bless.
"Train HARD, win EASY. Train Easy, win HARD". Hoping you all the best out there. Just continue on your aim to help the students as well as the
non-students to further enhance their math skills. God bless and More power AHMATH FTW!!!
