Why do the tricks work?!

Hello all,

It's been some time posting my updates here. With learning the tricks to solve the problems quickly,  the mentors suggested that it would be better if we can help the learner to understand the actual math behind the trick. That will help them to learn and explore more.

Taking the valuable suggestions, a new part called "curiosity clicks" has been added to the activity.

Let that evolve in time in this weeks, but before getting to that, we will see the math behind few math tricks we saw in the last post.

1) Square of a number just below 100.


2) Multiply any number with 5.


3) Multiply any number with 9.


4) Multiply any number with 11.


5) Square of any number ending with 5.


6) Square of any number just above 100.



You may please test the being developed activity here and also the code repository here.

Hello, As we make progress, we have our first game in place. The concept of the first game is explained below. Trick 01 : Square of any number ending with 5 Let us find the square of the any number ending with 5. Say x5. Step 01: Think of the number next to x.  Step 02: x * number next to x  Step 03: Put 25 at the end of the answer  Answer = Step 02 | 25 = x * ( x + 1) | 25  Example: Question: (45) 2 Step 01: Next number to 4 is 5 Step 02: 4 * 5 = 20 Step 03: Put 25 at the end of the answer Answer = 20 25 Implementing this game wasn't not our prime concern. We were more involved in defining a framework to implement as many tricks as we can. In that attempt, we have developed our first game. The learning was huge. Being the first one to be developed, we had overcome many difficulties and and also learned a lot. Few screenshots of the game are as follows, Initial menu screen Game screen Following this post, a short tutorial on developing

GSoC ends!

Hello all, Google Summer of Code 2017 has come to an end. In this due time, I evolved as a student pursuing a Bachelor of Commerce who can also do programming. Mind Math activity is in its last stages of development. A detailed report on the activity is available in its repository, here . I express my sincere gratitude to Tony Anderson, who mentored me throughout the project and helped me to overcome many odds. I had a huge sense of fear being a newbie to initiate a communication on a topic during the initial days. But Tony has helped a lot in this case and initiated conversation many times and also took much time in providing me with the feedback on the work. [Drafting...]
