Origination of Algebra

The Origin 

The origin of the word “algebra” is derived from the Arabic word الجبر al-jabr which comes from the title of a manuscript written by the mathematician Al-Khwarizmi in the 9th century. The root word means restoration or completion. The book title is “ الكتاب المختصر في حساب الجبر والمقابلة ” translated to The Compendious Book on Calculation by Completion and Balancing”. Algebra is the study of mathematical symbols and the rules for manipulating these symbols. One of the definitions of algebra is “the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations”. It is a good foundation before moving on to more complex part of mathematics. For decades, it has been used for many fields such as engineering, business, architecture, mathematics, science and more. 

The Importance

Algebra is one of the keys to understanding other advancements. In other subjects such as chemistry, physics, science, engineering, medicine, and economics depend on algebra. It teaches as beyond basic and is also the preparation before calculus and statistics. Learning algebra helps to develop our critical thinking skills as we’re trying to find the unknown answer to complete the problem. Furthermore, algebra can play roles in our every day including business, finance management, technology, cooking, sports, time management, etc.





Existence of Angles | Math

Angles is one of the elements of geometry. It doesn’t only exist in the math world but it was created with a purpose. Before reading all of these post, considered you have ten seconds to think about why angle exist and what the point of learning it for the real world.

Angles have different name considered of how many degrees it turns. There are varieties of types listed in the textbook such as acute, right, obtuse, straight, reflex and more. But what is the point of learning it to really apply to our real world?

Photography and Filming:

If you are a photographer,  you should know that there are different angles for taking a photo. If you don’t know or never learned angle it isn’t easy to take the photo without knowing where is the angle you want to take. When you learned and understand clearly about every type of angle, taking a photo in the angle you wanted to wouldn’t be hard at all. For filming, in the movie or video it must have different angle shot to put together with details without angle it will mess up around. With different angles in a video, it can make the video more interesting for the audience to watch.

If you are an engineer, geometry is very important to many factors to make your project better. Furthermore, an angle can be a very important element for those too. Due to the fact that the engineer must think about the angle that the building is facing and the sun. The right balance of sunlight and daylight in a building is crucial to people’s wellbeing. If an engineer doesn’t consider it properly, the building might end up to be overheated. For people’s health, they also really want to stay in place with natural sunlight to work better.  

Playing golf:

When you’re playing golf, what you have to know is the angled wrist. In order to swing to the path, it needs to have the position and the right angle throughout the swing. You need to learn the skill of putting the right angle of your wrist to swing it into the right hole.

Uses and importance of fraction in our daily life


Math is known to be one of the most important subjects in the world. It can involve or relate to our world and our life in different ways. Fraction as a part of this important subject is also crucial for our daily life. Without examples, you may still wonder or want to more so I have come up with some examples.

Imagine you are going to your grocery store with 200$. Due to your luck or special celebration, the store makes a special discount with 25 percent off the price in your spending. You may need to think of how much would you have to spend with the discount using a fraction.

It’s your friend’s birthday party and you would want to try and bake a beautiful cake to make that day even more beautiful. Can you picture wouldn’t it be bad without measuring your ingredients to bake the precious cake? Using fraction you will know how much of an ingredient you might need in a cup or spoon. After measuring and leave your cake in one of those baking stoves the decorations are ready for the birthday party.

Time is important in every single person’s life. With studying, working, family trip, hanging out with a friend or your own time you should manage your time wisely with a daily schedule. In the absence of fraction, it wouldn’t be as organized. Now let’s get make the schedule for your homework on weekend. From 6 o’clock to 7 o’clock half of ½ the hour you will spend on finishing your math homework. Another quarter of an hour which is from 6:30 to 7:30  you will spend on your computer science assignment. ½ of an hour or quarter of an hour using this method which is exactly fraction help you to organize and divide your time into section wisely.

Ratio and comparison



Imagine you want to compare the number of girls and boys in your math class. Example The students who are girls is 88 students and the boys are 80 students. When you write in ratio it should be 88:80. The reading form is 88 to 80. It could be simplified to 11 : 10. By using ration and simplified the number ratio play a really useful way of comparing the number of girl and boys students in the class to see the difference quickly. It is also similar to the fraction with the way we simplified them. The order of the ratio given in the exercise or form in words is also very important.

Example: Find the ratio of pineapple to strawberry. As you can see in the picture there are 6 strawberries and 4 pineapples. The correct answer would be 4 : 6 because the exercise or problem are asking you to arrange the ratio of pineapple to strawberry.


In math class this year it is harder than the last year. The book we are learning this round is Primary Mathematics 5A. We’ve learned more advance lesson about fraction, factor, multiplication, algebra and more. One of the most challenging lesson that most of the students were struggle was algebra. It requires us to think a lot to solve one algebra problem. After, spending time learning about it I think that is not that difficult if we try to do it. There are so many lessons that we are getting through right now. One of my favorite lessons is fractions. I feel comfortable to learned and solve the problem. There are some new strategies and knowledge in math that are being taught by the teacher. Not only that we use math book we’re also using online program learn. I use to be uncomfortable to solve a problem or catch up with the lesson before but right now I really love math because I spend my own trying to learn it a lot. I love how my teacher explains about each problem very clearly. Math is hard but it might get easier if you practice a lot.
