I think solving systems by elimination is the most complex one if you compared it to the other two. Because you need to take some steps to solve it. (Steps) 1. Adjust the formula to make it easier to calculate 2. Add or subtract ② from ① 3. Get x or y 4. Get the…

Function notation part two I learned function notation this week too. I made some questions for function notation and I’m going to introduce those this week’s blog post. I have noticed that all of this type of question can be solved just insert a number that is in( ). And you should check your…

I learned about function this week. On function, if there’s one input there’s also going to be one output. There are some relations on the below. These numbers are a little bit changed from a workbook. These all of the numbers are function. Because, if you look at the just input(or output) there’s no…

I learned the relationship between two quantities on this week. I put together things that I learned from this week below. I drew the graph. The domain is a range of x, and the range is a range of y. I also found a difference between Canada and Japan. When we write an Inequality sign. In…

<Difference between Japan and Canada> ~Factoring~ I learned some types of factoring this week. I am going to write this blog to focus on the difference in solving between Japan and Canada. Example problem:10×2+17x+3 In Canada, I learned like this. However, the Japanese learning style is a little bit different. Here is the Japanese…

Topic: Multiplication of polynomials part 2 I learned how to solve a little bit longer polynomials in this week. First, I’m going to write an example of a little bit longer polynomial. (2x+1)(x² +5x-8)=2x³+10x²-16x+x²+5x-8 =2x³+11x²-11x-8 We can use this diagram to solve it. I think we should not use algebra tiles for this question. Because…

In week 5, I learned about polynomial operations. I knew some new words this week. Leading coefficient… The number that is placed in front of first x of the polynomial Coefficient… a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. Constant… A fixed value. In Algebra, a constant is…
