About Subtraction
While solving the subtraction problems, people often make the mistakes, especially when the numbers needs to be subtracted from 1000, 10000, 100000 and so on.
Main errors happens when the numbers are borrowing from the neighbouring digit during the calculation in our normal school method.
The method I will share with you is actually originated from an ancient Indian Vedic Maths system.
To solve such kinds of subtraction sums, just remember this small vedic maths formula:
“LAST FROM 10, REST FROM 9”
Let’s start with an example
1000 ⇐Forgot these numbers
-289 ⇐Apply the formula here from right to left
———-
10-9 =1 [Last from 10, i.e. the last number (at unit place) should be subtracted from 10]
9- 8 = 1 [Rest from 9, i.e. rest all numbers (at subsequent places) should be subtracted from 10]
9-2 = 7
So the Answer is = 7 1 1-------------------- [Caution: Remember the sequence while writing the numbers]
Let’s try another
100000
-456
———–
Here in this example, there are 5 zero in the 100000 and below there are only three digits (456), so to match digits equal to 5 zero, just add 2 zero before 456 to make it 00456, and apply the formula
“LAST FROM 10, REST FROM 9”
10-6=4 --------[Last number subtracted from 10]
9-5= 4
9-4= 5
9-0= 9
9-0= 9 ------ [Rest all numbers subtracted from 9]
Answer: 99544
Tip: Total number in the lower row is equal to the total umbers of zero in the above row. If not, make it equal by putting the zero before the numbers.
