5x     = 300


                                     x      = 60

               So, the area of Mr. Idris' apple orchard is (x)2 = (60)2 = 3,600 unit area


               Get to know the properties of arithmetic operations on algebraic forms

               The operation of addition and multiplication of algebraic forms has several properties,

               including:


               1.  Commutative Properties
                   a + b = b + a

                   a × b = b × a
                   (Already shown before)

               2.  Associative Properties
                   a + (b + c) = (a + b) + c

                   a × (b × c) = (a × b) × c

                   (Please check)
               3.  Distributive Properties (multiply to addition)

                   a × (b + c) = a × b + a × c
                   or a(b + c) = ab + ac

















                   Example 3.1 Multiplication of Algebraic Forms
               Simplify the following algebra

                   1.  2a x 2b = …

                   2.  2(3   + 1) = …

                   3.  −6(2   − 3) = …

               Solution:

                   1.  2a x 2b = 4ab
