MMMR — What is that?

What did I learn last round??????

Ohh right, I learn about Mean, Median, Mode and Range. Almost forgot. Kakrona you baka!

Before jumping to the lesson, let me ask y’all one question! How are you doing? It’s been a long time since I’ve updated any work. I’ve been pretty busy lately and I don’t have any time to update. Okay, let’s get going with our lesson.

It’s not really a lesson, but it is what I have learned in class for round 3. 

Teacher: What does mean mean? 

Me: Huh? Mean? Mean means to convey, refer or aim for the knowledge that wanted to give to other people.

Teacher: Idiot!

Me: Nani Sureh? ( What are you saying in Japanese )

Teacher: Not this meaning.

Me: ( try again ) Mean means rude or you are acting disrespectful to another person.

Teacher: Still idiot!

Me: NANI? ( What in Japanese )

Teacher: Almost right, but not this.

Me: ( last try ) Mean means the average of set number

Teacher: Subarashii!!

Me: Go-gome teacher. What does “Subarashii” mean?

Teacher: Excellent!

Me: Arigato!

To get you back from my joke show up there, let’s me explain the four words here . Mean means the average of set number.

Median means the number in the middle of the set of numbers.

Mode means the number that most appear.

Last but not least is range. Range is the difference between the lowest and the highest number.

To understand deeper, you can do some problems that are given down there. The most important thing is “DON’T FORGET TO ARRANGE THEM FROM SMALLEST TO BIGGEST”

Enjoy and hope you like it.

Problem 1

The numbers that are given: 92, 45, 74, 29, 19, 87 and 56.

Find the mean, median, mode and range for the number that are given.l

Problem 2

The numbers that are given: 30, 100, 46, 99, 215 and 30

Find the mean, median, mode and range for the number that are given.l

Problem 3 — Challenge problem!

( I haven’t tell y’all about the formula of how to do this, but this is extra work)

There are 4 scores that Summer got from her learning. They are 25, 45, x and 93. The mean of the four scores is 50. Find the missing score.


Wrap up all lessons/ Round 5

This is the last round of my third years. Woohoo! I can’t believe it this fast. So far this year, I have learn a lot of things such as Calculations with numbers, fractions, decimals, surface area, ratios, measures and volume, percentage, angles, data analysis, rate and speed, and an introduction to algebra. In all of those things that I learn in this year, I think, I do best on fraction, decimals and surface area. I seem to be very focus with these topics. For me, they are the most easy topics to learn in math. The hardest topic for me in math is algebra. This topic is really difficult for me TT. The word that they are using is really tricky and sometime it really hard to understand since English is not my first language. For this round, we are most focus on data analysis and rate and speed. In my opinion, these two topics is not really hard or easy, they are medium level for me. Some words problem of this topics is easy to solve, but as I say, the sentence or question are tricky that is why it make it’s hard for me.

The conclusion, this round I enjoy learning math class because it’s not really difficult and it’s an important topic or lesson for me when I’m growing up or take a test for university 🙂

The difference between Percentage and Angle / Round 4

Math is one of the most important lesson to learn. You need math for your everyday living a lot. Examples, when you are going to the market, you need to buy some food and you need to calculate the price of the food that you buy. When you grew up and you want to take a job as a cashier, you need to know how to calculate too, even you use the machine to calculate the money.

Percentage is also a part of math. Let me tell you the introduction of percentage. Percentage is a unit that use to calculate thing easily. Usually, we always keep as hundreds. Every number that they want to use percentage, they always say 100%. Example, the population in Cambodia is 16.01 or 100%. In 2008, the population of Pursat province is about 442,973 and as percentage, it’s equal to 3.1% to the total population of Cambodia. That’s show, it is more easy to look at the percentage because percentage is short and easy, but for the actual number of the people is hard to remember. Down here is one of the example of Percentage.


Angle is “ the space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet” – Dictionary. In my own understanding, I think angle is use for measuring the area of something and it is the two line that meet together in the different direction or shape and it’s create the different angle. We also learn about the name of the two angles that is add up to 90 degrees or 180 degrees. Supplementary angle is angle that the two angles that sum is 180 degrees. Complementary angle is the two angles that plus together and the sum is 90 degrees. Angle is use for Engineering, architecture, building thing or designing thing.

Down here is the types of angle that we have learn. These are all the lesson that we have learn in this round.

Decimal / Round 3

A decimal is a fraction that is written in the form of a dot followed by one or more numbers which represent tenths, hundredths, and so on: for example .5, .51, .517. …simple math concepts, such as decimals and fractions”. Decimal is not a hard lesson to learn. I like decimal because the multiple and division decimal is not so hard as the fraction. Do y’all know who create Decimal? If no, you will get to know it today because I will tell you now.

John Napier was the one who creates decimal. He was a Scottish landowner known as a mathematician, physicist, and astronomer. Decimal fractions were first developed and used by the Chinese at the end of the 4th century BC, and then spread to the Middle East and from there to Europe. He was born in 1550 and died on April 4, 1617.

Ratio / Round 2

Welcome to Ratio!

Learn Ratio by yourself with this picture. Hehe, Kidding.

In Round 2 of our school, we learn Ratio. The ratio is useful with some many numbers that you want to make it smaller.


Fraction / Round 1

In our school, we divided our students into four different class and different time. I learn in 11:00 o’clock to 12:00 o’clock. In my math textbook I have learn Whole number, More Calculations with whole numbers, Fraction, Multiply and Divide fractions, Perimeter/Area and Surface area and Ratio. We learn from Primary Mathematics textbook that come from Singapore. I like word problem the most. In my class teacher always give us the word problems. I always can solve it with my friend. Sometimes I like to do Math problem by myself, so that I can easily solve it. Like the problems one below. I solve it with my classmates. I usually do the Math problems whenever I have free time.
