Hi,
I am mathematics Sensei.
I am a keen mathematics teacher. I have taught more than 1500 students in Japan and English speaking countries.
Love teaching maths but it takes time and cost.
It would be great if you can buy me a coffee so that I can spend your donation for my software update or other facilities.
I strongly believe that mathematics have the potential to make our world better place, and as long as I can afford time and money, I will keep teaching maths online.
Your support will make a difference in the world.
Cheers☕
