Disclaimer: this post might be a cheesy one, it will be more about ka Emil & me haha.

On the last Saturday of 2017, Ka Emil and I went to Marugame. After finished our meal, I opened my senior high school group and found that my friend gave a riddle. Since I was waiting for ka Emil to be ready to our next destination, I worked on that riddle. I worked with paper (Marugame receipt to be precise) and pen which I borrowed from ka Emil. I counted it manually, just because~ After I finished the riddle I gave my answer to the group. Then, ka Emil asked me what did I do? I showed him my draft, my manual problem-solving. Turned out, he was interested in the riddle and asked me to show him the riddle.

After packed our belongings, we walked from Marugame to Merdeka street (Yes, walked, by foot) We kept silent for a while and suddenly ka Emil said about the riddle, to confirm on how the system in that riddle work, what my answer is, and how to solve it. “Oh, my… I know you’re so silent because you’re thinking about it!!” Hahaha, I did not know that he would be interested in the riddle. “Yes. However, I try to solve it inside my mind.. by creating a mathematical formula of it ” he replied and told me some mathematical solutions he thought of, I didn’t remember exactly. I just laughed. He’s so funny!

Then we went to the brownies place, I told him to wait somewhere while I was buying the brownies (for myself, in case you want to know :p ). When finished, I met him at the restaurant part of the place. Turned out he’s still working on the riddle in his mind haha. Suddenly I had this feeling that I made a wrong calculation on my answer, then I checked my draft (the receipt) and yes I made a wrong calculation. I revised my solution and showed it to ka Emil. I made it neat enough that he could recognize the pattern. I knew there’s a pattern too. However, made it to some mathematical formula was too much work for me at the time hahaha. He recognized the pattern from my draft and voila! He made the mathematical formula easily (like less than 5 mins maybe). Then we exchange our answer and the answer from my draft/receipt and his formula was same, yeay haha. He’s so happy finding out the formula that he even open my group to answer the riddle and happily provide the mathematical formula explanation to the group!!! Hahaha


Here are some proofs of evidence.
This is the problem. Thanks, Hime!


My manual solution.. (on the back of receipt)


His solution…


He happily explained his solution in my group and astonished my friends 😂 #imsosmart #noguys #itshim


Here is the funny guy, so happy finding out the formula 😆

The smart guy, he’s so happy! #imhappyforyoutoo #LOL
