 in the podium because I will talk about the lessons I learned from Puzzles Math and Code and just, so my name is Joy Pass and you can, that's my github username, I don't tweet so you, I have a twitter account to that but I don't use it. So I work for Quipper which is an e-learning company and I work for their Philippine office and so, let's start. I think there are two kinds of people, ones that enjoy puzzle and ones that see it as a great source of headache. And similarly in math, some just play around with it like this one and no, math for the other people math stands as mental abuse to humans. So, who belongs to the left side, who belongs to the left side? A few people, how about to the right side? Wow. Okay, so I will talk about how my experiences affect me as a developer and no, this is not limited to knowing that the great ideas and algorithms come to you when you are taking a shower and so when I was a child of course I had toys and I had dolls but I enjoyed playing with puzzles and my dad used to create handmade puzzles like the one below so I really enjoyed and from there I learned that what seems impossible can be possible if you give your best so sometimes how can this work? I really enjoyed it. Fast forward to my schooling days, I can tolerate math but I have generally have this attitude. So, math, just solve your problems. And so, when math class is boring and other classes are boring, I doodle this on my notebooks in high school and I was trying to find how a night can cover the chess board. I was doing it for weeks until I finally found the answer. So, I was like, yeah. However, years later in another math class I discovered that this is actually a night's tour and there are 19, about 19.6 quadrillion solutions. I only found about five. So, I was like, what the hell? So, yeah, I realized, oh, so math is like a puzzle. So, I started to enjoy it. And fast forward, so this is the lesson that I learned from that stage. So, you may not be the first one to arrive at the solution but the fun of discovering things and the curiosity is very important. And fast forward, I became a math teacher in high school in the Philippines and those are my students and they are taller than me. And there came a point when I became so frustrated because no matter what I do, this is just so impossible. You cannot make people love math. So, I consulted my mentor and he said that even if you don't make them like math, you will teach them this lessons. The three piece, patience, persistence and perseverance. So, yeah, it's difficult but in solving a problem you have to have the skills and math slowly teaches us even if we don't know about it, math teaches us this. So, in conclusion, those lessons helped me becoming a web developer. So, there were tricky bugs that were hard to even reproduce or track but, you know, just try and try. And we learned not to give up easily when trying to achieve a goal and look at different perspectives. This is important not only in development but also in business and dealing with people. You have to look at how the other person feels or how your customers will react. So, maybe you like this thing but the other people doesn't like it. And value the learning process over the correct answer. And one very important thing, life is a puzzle. So, and math is like a big puzzle. So, never ever tell your kids math is difficult because they will suffer in school. So, thank you.
