How To Calculate Quickly With Jarimatic Method
Hi how are you, this time I @sucindi will give you a little knowledge for us all how to calculate fast using fingers.So let's learn so that we can teach our children at home.
For those of you who have sons and daughters who are in elementary school, surely they must master the Basic Mathematics lessons well, that is addition, Subtraction, Multiplication and Division. But sometimes there are still many children who have difficulty mastering this basic mathematics lesson, this is because they are saturated with the methods of mathematics lessons they learned, to overcome this then created a method of learning mathematics that fun and educational method of Jarimatika, hmm what the heck in the mean with jarimatika? Jarimatika is a way of calculating mathematics by using the fingers of the hand. The mathematical counting operation is addition, subtraction, multiplication and division. This method was developed by Septi Peni Wulandani around 2004. The logic of finger calculation is similar to the logic of abacus usage. And since the year 2004 until now this method is very popular finger show even popping places - the place that offers tutoring services with the method of fingerprint, of course not free, you must pay expensive to register your sons in the course. then why do not you learn this method of fingerprint yourself and then teach yourself to your sons at home.
Come Learn how to Calculate Quickly With Jarimatika Method!
The Basic Concept of Jarimatika
In the finger, the right hand is used to symbolize the unit, while the left hand is used to symbolize dozens.
Use of the right finger
symbolizes the value of the unit
-Number 1 is represented by the index finger of the right hand.
-The 2nd figure is represented by the right index finger and middle finger.
-The 3rd figure is represented by the index finger, middle finger and ring finger of the right hand.
-The 4th figure is represented by the index finger, middle finger, ring finger and the little finger of the right hand.
-The figure 5 is represented by right thumb finger.
-The number 6 is represented by the thumb and index finger of the right hand.
-The figure 7 is represented by the thumb, the index finger and the middle finger of the right
hand.
-The number 8 is represented by the thumb, index finger, middle finger and ring finger of the right hand.
-The number 9 is represented by the fifth right fingers.
The same use for the left hand finger, with the value of tens,
Use of the left finger
symbolizes the value of tens
Figure 10 is represented by the index finger of the left hand.
-The number 20 is represented by the index finger and the middle finger of the left hand.
-The number 30 is represented by the index finger, middle finger and ring finger of the left hand.
-The number 40 is represented by the index finger, middle finger, ring finger and the little finger of the left hand.
-The number 50 is represented by left hand thumbnail Figure 60 is represented by the thumb and left index finger.
-The figure 70 is represented by the thumb, middle and left index finger of the left hand.
-The figures 80 are represented by the thumb, index finger, middle finger and left hand ring finger.
-The figure 90 is represented by the five fingers of the left hand.
Operation reduction 24 - 12 = 12
The left hand: the middle finger (-10), the right finger: close the little finger and ring finger (-10), the right finger: close the little finger and ring finger (- 2) the result of the left finger is open only the index finger (10) and the right finger is open only the index finger and middle finger (2) read 12.
Sum Summing Operations 13 + 11 = 24
Left hand opened index finger (10) and right hand opened index finger, middle finger and ring finger (3) left hand in open middle finger (+10) and right hand opened pinky finger (+1) result, left hand open two fingers (20) and the right hand is open four fingers (4) read 24.
Multiplication Operations
The following is the multiplication method using the finger (jarimatika). if you understand well the rules in the multiplication below, you do not find it difficult to try to multiply by numbers other than the example we give below. Hopefully this can be useful for parents of students in teaching multiplication for their sons and daughters.
MATCHES 7
A. AREA 7 WITH 1, 2, AND 3
Example: Multiplication 7 X 2 and 7 x 3
B. THE ARRANGEMENT 7 WITH 4, 5, 6, 7, 8, 9, 10
Example: Multiplication 7 x 4 and 7 x 6
MATCHES 8
A. ARRIVAL 8 WITH 1, 2, 3, 4, AND 5
Split Operations
The process of division is the opposite of multiplication. In the division operation by using the method of fingerprint in this study only discuss the division of number 2 with number 1 number.
Finger division formation
The finger of the fist is closed, the other finger is opened its value = 6
The little finger and ring finger is closed, the other finger is opened its value = 7
Little finger, ring finger and middle finger closed, the other finger opened value = 8
Thumbs open the other finger closed value = 9
All fingers are closed value = 10
Thumbs open value = 1
The thumb and forefinger are opened in value = 2
Your thumb, forefinger, and ring finger are opened in value = 3
Thumb, index finger, ring finger, and middle finger opened value = 4
All fingers are closed value = 0
The subtracting factor on the index number changes according to the following conditions:
If the index is 5 = 10, then the reducing factor is 0
if the index is 4 = 9, then the reduction factor is 5
if the index is 3 = 8, then the reduction factor is 10
if the index is 2 = 7, then the reduction factor is 15
if the index is 1 = 6, then the reduction factor is 20
The formula of division in jarimatika as follows:
Basic formula: (NS + 10): S1 = S2
Information :
NS = the unit value of the divided number
S1 = dividing unit (finger opening)
S2 = number results (closed finger)
Note:
Not all numbers can be divided by way of finger, some numbers that can not be operated by way of finger is a number having unit value which is not divisible by S1 (divider unit)
The divisor unit used is 3 and above. If the unit value of the divided number (NS) divided by the divisor unit (S1) is not divisible then the value of the unit must be increased by 10 in order that the unit value can be divisible. For example, unit 6: 4 is the value not divisible, then unit 6 must be added 10 to 16: 4 = 4 thus, the value of the unit can be divisible.
The left open finger position is the result of the NS divider with S1, and the opened left finger is the end result of the division of the number.
Example 1:
54: 9 = ......
The process of counting finger division as follows:
Step 1: little finger, ring finger, middle finger, and index finger closed thumbs open the position of the divisor, in the example of the divisor is 9
Step 2: the unit value of the divided number (54) is 4
Step 3: unit value 4 divided by the value of the unit divided by the number of open right hand fingers (S1) that is 1. 4: 1 = 4 result of this division to know the position of the left open finger (B2), which is 4 fingers started
Step 4: divisor result
The result of 54: 9 can be seen in the pharmacology of fingerprinted by the left hand
Thus, the result is 54: 9 = 6
of the thumb
Example 2:
81: 9 = .....
The process of counting finger division as follows:
Step 1: little finger, ring finger, middle finger, and index finger closed thumbs open the position of the divisor, in the example of the divisor is 9
Step 2: the shared number (81)
81 has a unit value of 1. the unit value is divided by the number of open right hand fingers (B1), ie 1.
1: 1 = 1 result of this divider to know the left open finger (B2) is 1 finger starting from the thumb
Step 3: share results
this is my knowledge that I can after reading the book, My job is a teacher, so I am always involved in the world mathematics.Picture that I post here I can from the book I read. So do not say I'm a Flagiat because this book is in circulating at school I teach, my goal is writing so that more parents who can teach the their children mathematics at home.
