Khanacademy is the best sources for me to learn math. Khanacademy helps me to be an independent learner, there are questions to practice and if I struggle, there are a oodles of videos that going to guid me through each section. 

For the round two of the school year, my class is focusing on transformations, congruence, similarity, and right triangle & trigonometry. 


After the PSAT Bootcamp, everything’s kind of instance. Literacy lesson is getting harder and math is getting tougher and tougher. I listed down what I want to learn in math class, which is my focusing area for this school term.


  • Complex numbers
    • Imaginary numbers
  • Arc Lengths and Area of a Circle Sector
  • Probability


When it gets to complex numbers, it sounds so perplexing to me and everything is just like one big maze that I have to drill into my fried brain. The second formula doesn’t make sense to me because the square numbers can’t be negative, nevertheless have to remember it.

I still use Khanacademy as my online learning, which is super, super helpful.



Things are getting interesting in Khmer Class. I was trying to write poems for the whole the past month (November 2017) because my Khmer teacher said so. I finished four poems and they were about, Banteay Meanchey Province, Perfect Husband, Teacher Sokha (My Khmer Teacher) and about my mother. My favorite one so far is about my mother. I tried to describe every single situation that she had been plus she’s one of my biggest inspirations.

English version

She’s tired and hot just because to build the education for her children. She’s famishing and her body was drained and she doesn’t want to buy any food for herself because she wants to keep all of that money for her children. 

The women who meant a lot to me and she’s taking all of the pressure just because of her kids. She tries to every single way in every single situation to find cash to support the family. She doesn’t care that her life is about to burst into death.

No one knows that she’s sick, she’s taking another pressure of her sickness. No one knows that she sleeps on the mat and no one is taking care of her. 

She wants her kids to be good like others, therefore she must work harder and harder, even though she sick. 

After I know that I will try harder in school, so she doesn’t have to misgive about me.

My mother is one of the girls, who always believe in me and make me move forward without wasting any of my time.  I will do it because of her.

Study hard is the candle to light up my life and I’m the only person that I can depend on.

My mother used to tell me that if I can’t focus on school, I can think of her because she’s my inspiration.

Dear mother, I am sorry for all of the mistakes I’ve made. I will try to fix it and do good things while I’m young.

I really really want to say thank you to my parents, especially my mother. I’m trying to show what I mean from the inside of me by this poem.


Sometimes I feel like I like math and sometimes I don’t and I don’t know why too. I learn math by using books and websites. I try to do a lot of math works so I could say that math is my passion, but it takes so long, nevertheless I’m in the process of it. Currently (2017 – 2018) I study dimensions math common core 7B book and my favorite chapters is linear graphs and inequalities. Basically, is you are solving for the variable (x).

Examples: Emilio can buy x books at $5 each with $26. Then the total cost of the books bought must not exceed $26. Thus $3x is less than $26. Mathematically we write

5x < 26

we call “3x < 26” an inequality. It is a linear inequality with one variable x. all values of x that satisfy the inequality are called the solutions of the inequality. 

What are the values of x that will satisfy the above inequality? By inspection, 

5 x 1 = 5 < 26, 5 x 2 = 10 < 26, 5 x 3 = 15 < 26, 5 x 4 = 20 < 26, 5 x 5 = 25 < 26, 5 x 6 = 30 > 26

Therefore, x 1, 2, 3, 4 and 5 are solutions of the inequality 5x < 26 but x = 6 is not a solution.

So Emilio can buy either 1, 2, 3, 4 or 5 books.
