The operation to find the difference between two numbers is called subtraction. Let us know some facts about subtraction that will help us learn how to subtract large numbers.

We know that subtraction takes something away from a group of things. The terms used in subtraction are Minus, Less, Difference, Decrease, Take Away, Deduct. In finding the difference, we write the larger of the two numbers given above and subtract it.

1. The subtraction with small numbers can be worked out horizontally.

Example: 8 – 5 = 3

24 – 4 = 20

2. Large number subtraction is calculated vertically. Numbers are written under the place value board.

Example: Th HTO

8 6 7 2

– 5 4 3 2

3 2 4 0

3. If a zero is subtracted from a number, the value of the number does not change.

Example: HTO

2 5 8

+ 0

2 5 8

4th 1 subtracted from a number gives the predecessor of the number as the difference.

Example:

5. The number from which to subtract the other number is called the minuend. The subtracted number is called the subtrahend and the answer is called the difference.

Example:

6th If the subtrahend is missing, the difference is deducted from the minuend.

Minuend – difference = subtrahend.

Example:

Functionality:

7th To find the missing minuend, add the difference to the subtrahend.

Difference + subtrahend = minuend

Example:

Functionality:

Note: Here in progress we have Difference + Subtrahend = Minuend. made
