    • Operation Of Algebraic Form
    • I. Operation Of Addition and Subtraction The Properties of Addition Operation  a) Commutative : a + b = b + a  b) Distributive : i) a b + a c = a( b + c ) ii) a b – a c = a ( b – c )  c) Associative a + b + c = ( a + b ) + c = a + ( b + c ) = ( a + c ) + b
    • Examples 
    • solution  a. (3a- 2 ) + ( 7a + 6) = (3a + 7a) + ( -2 +6) = 10 a + 4 Vertical method : 3a - 2 7a + 6 + ------------ 10a + 4
    • Find others solutions 
    • c. 2a + 3b and 3a- 2b
    • d. 5m -7n + 4 and 2m+3n -9
    • 2. Subtract 
    • Solution  a. 4b- 7 from 5b + 2  ( 5b + 2 ) – (4b- 7) = (5b- 4b) + (2-(-7) ) = b + 9 Vertical method 5b + 2 4b – 7 – _______ b + 9
    • Find The Others solutions !  Who would like to try to fin solution ?
    • I have to be a success student
    • II. Multiplication 
    • Exercises ( do by discuss) 
    • Remember  Be a student so long as you still have something to learn, and this will mean all your life. ~Henry L. Doherty (“Jadilah penuntut ilmu selama kau masih memiliki sesuatu untuk dipelajari, dan hal ini akan menjadi tujuan seluruh hidupmu”)  I am learning all the time. The tombstone will be my diploma. ~Eartha Kitt (“Aku belajar setiap waktu. Batu nisan akan menjadi ijazahku”.)
