My name is Antonio Sánchez Chinchón and I live in Madrid, Spain.

I like cooking because I love eating. I like playing banjo because I love music. I like doing silly things because I love my children’s laughter. I like doing this blog because I love mathematics. All these things make my life worth of living.

You can find me in hello@fronkonstin.com where I will answer all your emails, be sure. All your comments are more than welcome.

Thanks to all of you who spend your time reading my entertainments.
