Operation Multiplication on Algebraic Form [1945900] In Basic Mathematical Model we have previously studied together about operation of addition and subtraction on algebraic form . So this time we move on to another form of counting operation that is about multiplication on algebraic form . In class VII you must have learned about the multiplication of algebraic forms. Do you still remember it? In the discussion this time, will be explained multiplication of a number with the form of algebra tribe two. Multiplication on algebra can be solved by using the multiplicative distributive properties of addition. [1945907] Multiplication of a Number with a Form of Tribal Algebra When bx + c [1945901919] is a common form of two terms with b ≠ 0 multiplication of numbers a with bx + C would be like this: a (bx + c) = abx + ac To make it easier to understand it, we now immediately learn how to solve this example of the following algebraic multiplication: Example Problem 1: Describe the following algebraic forms: [1945901] 3] a. 2 (x + 1) b. 3 (-4p - 5) c. Completion:

[194590]] [194590]

Settlement:
a. 2 (x + 1) = 2x + 2
b. 3 (-4p - 5) = -12p - 15
c. -4 (-2x - 1) - 3 (x - 2) = 8x + 4 - 3x + 6
= (8 - 3) x + 4 + 6

We can examine the above equations correctly or falsely by replacing the variable x on the left or right side by using any value. If the results of the calculation of the left and right segments sa, a, then the similarity can be said to be true. For example:

[1945909]

2 (x + 1) = 2x + 2 we use x = 0
2

It turns out that the results on the left and right are equally 2, meaning the similarity is true.

[1945907]
Example Problem 2:
A rectangle, a long side- Side of 5 cm and (2p +2) cm. Determine the extent of the rectangle!
Solution:
If the area Rectangles are called L,
L = 5 x (2p + 2) = (5 x 2p) + (5 x 2) = 10p + 10
Thus, the area of ​​the rectangle is (10p + 10) cm 2


That is a very simple explanation of multiplication on the algebraic form. For further material will be discussed about The Multiplication of Tribes Two in the Form of Algebra.

Units of Size The number of Lusin, Gross, Rim, and Kodi

Unit Size The Number of Lusin, Gross, Rim, And Kodi - When carrying out your daily activities you must have heard some terms like Lusin, Gross, Rim, and Kodi in mathematics the term is called a unit of measure of quantity or quantity. This unit is commonly used to express the number of items or objects. For those of you who do not know or have not memorized by the size of the unit, let us study it together by listening to the discussion The Basic Mathematical Formula on the following unit size sums: The most commonly used unit of measure quantities is : 1 dozen = 12 pieces 1 gross = 144 pieces = 12 Lusin 1 score = 20 pieces ] 1 rim = 500 glue Bar The use of units of measure of the number of Lusin, Gross, Rim, and Kodi The above sizes are usually used in accordance with certain types of goods, for example: Lusin The term dozen is more often used to express the number of items such as glasses, plates, spoons, jars, and so on.

Example Problem Arithmetic Social About Discount / Rebate

Example Problem Arithmetic Social About Discount / Rebate - the meaning of rebates are rebates granted to a product or service. We are more familiar with rebates as a discount. You'll often see at the supermarket or supermarket there are a lot of rebates or discounts, it is an example of a rebate. If you are curious about how to calculate the price cuts, the Mathematical Formulas Basic will give his review to you through examples to the following: Example Problem Discussion and Arithmetic Social About Rabat Example Problem 1 Melly want to buy a dress for Rp 120,000. It turned out that the clothes receive a rebate of 20%. What is the size of the rebate? Answer: clothes Price: Rp 120,000 Rabat: 20% x 120,000 = 20/100 x 120,000 = 24,000 Thus, rabatnya amounted Rp.24.000 Example Problem 2 [1945901million] A Shop, gives a 5% discount for every purchase math book. If a math book has a price of Rp. 85,000. what is the price of the book after the discount?...
