Tugas UTS : Matematika Level IGCSE
My impressions are:
In the course of the study IGCSE maths using English I get a lot of
knowledge and can understand math words in the English language ,
how someday I can teach mathematics in English , although not all of
them. I understand ...
I do not understand why because this course should be able to use English
.. when persentasi in class debriefing should use English every week .
But I can understand if there are words that I never learned and find
meaning in Indonesian dictionaries translate through .
The hope :
IGCSE maths should be further enhanced UAS learning until later , because
this lesson is very useful for our students in the future in teaching .
In this course I hope during school hours had begun , faculty and students
should be active in the English language instead of using Indonesian ,
because in this case the lecturers and students learn the English
language fluency ,
and I hope also to get the best value in the eyes of this college ..

3. E. Teaching Materials
1. Apperception
Before discussing the arithmetic operation on the algebra should first
understand the multiplication rate constants and a lot of numbers in a variable
substitution from many tribes. For more details see the following example:
a. 2 (𝑎 + 3) = 2𝑎 + 6 → distributive properties
b. − (𝑥 − 3) = −𝑥 + 3
c. 3𝑚(𝑥 + 2 𝑦 + 3) = 3𝑚𝑥 + 6 𝑚𝑦 + 9𝑚
If the algebraic form 3𝑥 + 5 𝑦, the variable 𝑥 is replaced by 2 and the variable
y is replaced by 4 then obtained:
3 𝑥 + 5 𝑦 = 3 (2) + 5 (4)
= 6 + 20
The process of replacing a variable with a number called the substitution
process.
2. The Core Material
Also known in the form of algebraic arithmetic operations such as addition,
subtraction, multiplication, division and reappointment. To more details will be
outlined as follows:
a. Algebra Forms
Forms 5𝑥 + 2𝑦 + 3𝑧, 2𝑥2
, 4𝑥𝑦2
, 5 𝑥2
− 1, and (𝑥 − 1) (𝑥 + 3) is called the
algebra . The terms contained in the algebra is as follows.
1) Variables
A variable is 𝑎 symbol substitutes 𝑎 number of unknown value clearly.
Variables are usually denoted by the letters 𝑎 , 𝑏 , 𝑐 , . . . , 𝑧 .
Example :
Variables of 5𝑥 + 2 𝑦 is 𝑥 and 𝑦
Variables of 2𝑥2
+ 4 𝑥 − 12 is 𝑥

4. 2) Constants
Is the rate constant of a form of algebra in the form of numbers and no load
variable .
Example :
Constants that exist in 2𝑥2
+ 3 𝑥𝑦 − 8 is − 8
Constants that exist in 3 − 4𝑥2
− 𝑥 is 3
3) Coefficient
Coefficients in the algebra is the number of variables inherent with a tribe in
the form of algebra .
Example :
Coefficient of 𝑥 that of the 5𝑥 + 3 𝑦2
𝑥 is 3
Coefficient of 𝑥 that of the 2𝑥2
+ 6 𝑥 − 3 is 6
4) Rate
Rate is variable and its coefficients or constants in the form of algebraic
operations are separated olrh sum or difference signal .
One tribe is a form of algebra that are not connected by the number sign or
difference operations .
Example :
3𝑥 , 4𝑎2
− 2𝑎𝑏
Is the algebra of two parts connected by a token amount or increment
operation.
example :
𝑎2
+ 3 , 𝑥 + 2 𝑦 , 3𝑥2
− 5𝑥
Is the algebra of three parts which are connected by two operations sum or
difference signal .
Example :
3𝑥2
+ 4 𝑥 − 5 , 2𝑥 + 2 𝑦 − 𝑥𝑦 .
Algebraic forms that have more than two tribes called many tribes or polinim.

5. b. Summation Algebra and Reduction
Properties of addition and subtraction on integers also apply to the algebra
but addition and subtraction operations on ajabar form can only be done on similar
tribes alone. Operations of addition and subtraction in the algebra can be solved using
the distributive properties.
Example:
1) 3𝑥 + 5𝑥 = (3 + 5)𝑥 = 8𝑥
2) 5𝑎 − 3𝑎 − 2𝑎 + 4𝑎 = (5 − 3 − 2 + 4)𝑎 = 4𝑎
3) 7𝑎 + 5𝑏 + 𝑎 − 2𝑏 = 7𝑎 + 𝑎 + 5𝑏 − 2𝑏
= (7 + 1)𝑎 + (5 − 2)𝑏
= 8𝑎 + 3𝑏
Addition operation on the algebra above can not be done because the tribes
are not similar, is 5𝑥, 3𝑦, and 6 were not similar.
Subtract the following algebraic form.
a) 8𝑥 − 4𝑦 from 5𝑥 − 7𝑦
b) 6𝑥2
+ 5𝑥 + 2 from 7𝑥2
+ 2𝑥 − 3
Completion:
a) 5𝑥 − 7𝑦 − (8𝑥 − 4𝑦) = 5𝑥 − 7𝑦 − 8𝑥 + 4𝑦
= −3𝑥 − 3𝑦
b) 7𝑥2
+ 2𝑥 − 3 − (6𝑥2
+ 5𝑥 + 2) = 7𝑥2
+ 2𝑥 − 3 − 6𝑥2
− 5𝑥 − 2
= 𝑥2
− 3𝑥 − 5
What if the algebraic sum operation occurs in fractions?
Operating principle is the same as the sum of fractions, followed just a
matter of form variables aljabar.Contoh:

also apply this concept to define multiplication and division algebra form tribes.
