Subtraction – What is Subtraction?
Subtraction is the method of finding difference between two numbers. Subtraction is opposite of addition. Subtraction is represented by minus (-) symbol.
Subtraction is useful in finding how much a number is larger or smaller than a given number. Subtrcation in Arithmetic is used in calculation of remaining amount or the money you have left with you after you spend some on purchasing goods.
In counting we can obtain previous number by subtracting 1 from the next number. The previous number is called predecessor of next number. For Example, we can get 3 by subtracting 1 from 4 i.e. 4 – 1 = 3. Hence, 3 is called predecessor of 4.
In the image attached below, there are 8 slices of pizza. Three slices are taken away thus we are left with 5 slices of pizza only.
Example: Mohan has 10 rupess in total. He spent 4 rupees to purchase a pen. How much money does he has left now?
Initially Mohan has 10 rupees
Money spent by Mohan to purchase pen = 4 rupees
Hence, Money left with Mohan = 10 – 4 = 6 rupees
