Math Addition Trick for Adding Two Digit Numbers

Let us begin with the basic method of adding two numbers
Take the example of 71 + 69
This is the usual method which we do with the help of pen and paper
Are you interested to do these calculations mentally?
If your answer is yes,then read below to learn the trick.
Trick:
In addition, adding 10 to a two digit number is easy as we just need to increase the digit in the tenth place by 1. 12 + 10 is 22,34 + 10 is 44 and so on.
We use the same rule while adding any two numbers.To be clear, see how 71 and 69 is added
Method 1:
Step 1:
71 + 69 can be written as 71 + 70 -1
In this step, 69 is split as 70 and 1
Step 2:
Addition of 71 + 70 is easy which gives 141 ie 71 + 70 = 141
Now subtract 1 from 141 ie 141 - 1 = 140.
This gives the answer i.e. 71 + 69 = 140
Method 2:
Alternatively, the below method can also be used.The choice of method depends on the numbers that are added
Step 1:
71 + 69 can be written as 71 + 60 + 9
In this step, 69 is split as 60 and 9
Step 2:
Addition of 71 + 60 is easy which gives 131 ie 71 + 60 = 131
Now add 9 to 131 ie 131 + 9 = 140.
This gives the answer i.e. 71 + 69 = 140
When you practice this, you can increase the speed and improve your addition skills.Try some practice questions

Finger Multiplication of 6,7,8,9,10 Time Tables

Place your fingers as in the below image and consider the value of fingers in each hand to be 6, 7, 8, 9 and 10 - in the order from small finger to thumb.




Example
Consider the multiplication of 7 × 8.
Make the finger numbered 7 in the left hand to touch the finger numbered 8 in the right hand.



Step 1:
Now in the left hand, count the finger which is touching (7) and the ones below that = 2 fingers
Similarly in the right hand, count the finger which is touching (8) and the ones below that = 3 fingers
Add the above counted fingers = 2 + 3 = 5 fingers
Multiply the number by 10 = 5 × 10 = 50 -----> (1)

Step 2:
In the left hand, count the fingers above the touching finger = 3 fingers
Similarly in the right hand, count the fingers above the touching finger = 2 fingers
Multiply both = 3 × 2 = 6 -----> (2)

Step 3:
Add (1) and (2),
= 50 + 6 = 56
So, the answer for 7 × 8 = 56 which is easily found through the above trick.

Note:
If there is no finger above the considered (touched) finger, then consider the value as zero (0).

Play the same for the below multiplications
6 × 6 = ?	6 × 7 = ?	6 × 8 = ?	6 × 9 = ?	6 × 10 = ?
7 × 6 = ?	7 × 7 = ?	7 × 8 = ?	7 × 9 = ?	7 × 10 = ?
8 × 6 = ?	8 × 7 = ?	8 × 8 = ?	8 × 9 = ?	8 × 10 = ?
9 × 6 = ?	9 × 7 = ?	9 × 8 = ?	9 × 9 = ?	9 × 10 = ?
10 × 6 = ?	10 × 7 = ?	10 × 8 = ?	10 × 9 = ?	10 × 10 = ?

Finger Multiplication of NInth Time Table

Finger Multiplication of Ninth (9th) Time Table

Place your fingers as in the below image and number the fingers from 1 to 10. Example Consider the multiplication of 4 × 9. Step 1: Here 4 is to be multiplied by 9. So, fold the 4th finger and count the ones before the folded finger. Number of fingers before the folded finger = 3 fingers Multiply the number by 10, = 3 × 10 = 30 -----> (1) (as shown in the below figure) Step 2: Count the fingers after the folded finger = 6 -----> (2) (as shown in the below figure) Step 3: Add (1) and (2), = 30 + 6 = 36 Therefore the solution to our problem 4 × 9 = 36 is easily found using the above trick. Note: If there is no finger below/above the considered (folded) finger, then consider the value as zero (0). Play the same for the below multiplications 1 × 9 = ? 2 × 9 = ? 3 × 9 = ? 4 × 9 = ? 5 × 9 = ? 6 × 9 = ? 7 × 9 = ? 8 × 9 = ? 9 × 9 = ? 10 × 9 = ?

Angel Number 421

Rules

   Step 1  
 Select any whole number. 
   Step 2  
 If it is an even number, divide by 2; if it is odd number multiply by 3 and add 1. 
   Step 3  
 Repeat the process mentioned in step 2 until you get the loop value 4, 2, 1 in 
 repetition. 

Example

  Whole number is 15. 
  15 is an odd no; so (15 × 3) + 1 = 46 
  46 is an even no; so 46 / 2 = 23 
  23 is an odd no; so (23 × 3) + 1 = 70 
  70 is an even no; so 70 / 2 = 35 
  35 is an odd no; so (35 × 3) + 1 = 106 
  106 is an even no; so 106 / 2 = 53 
  53 is an odd no; so (53 × 3) + 1 = 160 
  160 is an even no; so 160 / 2 = 80 
  80 is an even no; so 80 / 2 = 40 
  40 is an even no; so 40 / 2 = 20 
  20 is an even no; so 20 / 2 = 10 
  10 is an even no; so 10 / 2 = 5 
  5 is an odd no; so (5 × 3) + 1 = 16 
  16 is an even no; so 16 / 2 = 8 
  8 is an even no; so 8 / 2 = 4 
  4 is an even no; so 4 / 2 = 2 
  2 is an even no; so 2 / 2 = 1 
  1 is an odd no; so (1 × 3) + 1 = 4 
  4 is an even no; so 4 / 2 = 2 
  2 is an even no; so 2 / 2 = 1 

  So the loop 4..2..1 goes on and on.

Tip : The angel number 421 is the smallest prime formed by the two powers in logical order from right to left.

Day of the Date

Day of the Week:
January has 31 days. It means that every date in February will be 3 days later than the same date in January(28 is 4 weeks exactly). The below table is calculated in such a way. Remember this table which will help you to calculate.

January	0
February	3
March	3
April	6
May	1
June	4
July	6
August	2
September	5
October	0
November	3
December	5

Step1: Ask for the Date. Ex: 23^rd June 1986
Step2: Number of the month on the list, June is 4.
Step3: Take the date of the month, that is 23
Step4: Take the last 2 digits of the year, that is 86.
Step5: Find out the number of leap years. Divide the last 2 digits of the year by 4, 86 divide by 4 is 21.
Step6: Now add all the 4 numbers: 4 + 23 + 86 + 21 = 134.
Step7: Divide 134 by 7 = 19 remainder 1.

Age Calculation

Age Calculation

Age Calculation Tricks:
Step1: Multiply the first number of the age by 5. (If <10, ex 5, consider it as 05. If it is >100, ex: 102, then take 10 as the first digit, 2 as the second one.)
Step2: Add 3 to the result.
Step3: Double the answer.
Step4: Add the second digit of the number with the result.
Step5: Subtract 6 from it.
