Algebraic operation (Operasi Aljabar)

  1. 1.  Competence Standard (SK): 1. To understand the Operation Of Algebraic Form, Relation, function, and linear equation ( Memahami operasi bentuk aljabar, relasi, fungsi dan persamaan linear)  Basic Competence (Kd) : 1.1 Doing Algebraic Operation (Melakukan operasi bentuk aljabar) Operation of Algebraic Form
  2. 2.  - solve the operation of addition, subtraction by like terms or unlike terms  Use algebraic concept in problem solving Objectives : After learning this chapter, students able to:
  3. 3. In Our daily Life  There are many daily problems that can be solved using the algebraic concept  Such as : find of fuel needed by a motorcycle vehicle to travel a certain distance  Identifying someone’s age  Identifying the time needed to cover certain distance  Finding the formula of a pattern and the price of an item
  4. 4. Manfaat Belajar Aljabar Ada banyak masalah sehari-hari yang dapat diselesaikan dengan menggunakan konsep aljabar Seperti:  Menemukan banyaknya bahan bakar yang dibutuhkan oleh kendaraan sepeda motor untuk perjalanan jarak tertentu  Mengidentifikasi umur seseorang  Mengidentifikasi waktu yang dibutuhkan untuk menempuh jarak tertentu  Menemukan rumus /pola untuk harga satuan pada aritmetika sosial
  5. 5. Before continue, let’s remember about :  Algebraic form  Terms, like terms, unlike terms  Variable  Coefficient  Constant  Factor  Operation of numbers
  6. 6. 1.Consider algebraic form in the following table, and then fill in blank…. BentukAljabar koefisien variabel konstanta Banyaknya suku a. 5a a. 7xy- y -8 a. 5x-3y+1
  7. 7. And…. - Monomial - Binomial - Trinomial - Polynomial - Let’s check your memories 
  8. 8. Find the like terms in the following algebraic forms 
  9. 9. Jangan lupa isi identitas pribadi/ kelompok   Nama : ..........................................  Kelas : ..........................................  No. Absen : ..........................................  Nilai : ..........................................
  10. 10. Remember : “Inch by inch Math is Cinch But Yard by yard that’s so very Hard “ (Prof.Dr. Viji, lecture of math at SEAMEO RECSAM Malaysia ). “The Secret of Success in Life is for a man to be ready for his opportunity when it comes” (Earl Beaconsfield)
  11. 11. llustrations of daily life count the birds that are in each cage add the cat is in the cage and the bird is on the outside Consider the following pictures
  12. 12. Find the solution of following addition Twoo cats are in a cage A white hawk is in a cage
  13. 13. Consider the following pictures how many people and how many goats in each image?
  14. 14. Do you understand about the concept of addition of Algebraic expression ?
  15. 15. Let’s discuss these following problem 
  16. 16. Let’s make conclution  Syarat operasi penjumlahan dan pengurangan pada bentuk aljabar adalah : (dan untuk mempermudahnya lakukan….)
