Adding and Subtracting Integers

In the previous post we have discussed about List Prime Numbers and In today's session we are going to discuss about Adding and Subtracting Integers, Set of positive and negative numbers is known as integers except fraction and decimal numbers. For example: -3, -2, -5, -6, 0, 2, 8, 10, 12, 17, 20 and so on.

In the above examples all the numbers are in integer form. The number 0 is also an integer number. There are two types of integer which are positive and negative integer. All the numbers which are greater than zero is said to be as positive integer. For example: 3, 4, 7, 9, 11, 15, 17, 18, 21, 50, 502 and so on all are the positive integers.

And all the numbers which are less than zero is said to be negative integers. For example: -3, -6, -7, -11, -13, -15, -16, -18, -21, -50, -504 and so on all are the negative integers. Now we see some steps of Adding and Subtracting Integers. First we see how to add integer number. To add integer’s numbers we have to follow some of the steps:

Step1: To add two integers’ numbers first of all we see the numbers; all numbers should be positive or negative number.

Step2: There should be no fractions values.

Step3: Now add all the given positive and negative integers.

Let’s see how to subtract integers. Now we see some steps for subtracting integers;

To subtract the integers we need to follow some steps:

Step 1: To subtract integers first of all we see all the given numbers, all the given number should be positive or negative integer number.

Step 2: Fraction numbers and decimal numbers cannot be included in the integer numbers.

Step 3: Subtract all the given positive and negative integers.

For example: Subtract the number, if the numbers are (-14, -18)?

Solution: when we subtract any integer number we have to follow all the above steps:

Given, (-13, -17), If we subtract -14 - (-18) = -14 + 18 = 4

Let’s see inverse function calculator, as we know that it is online tool which is used to convert the domain of a function to the range and range of a function to the domain. Before going the examination hall go through the cbse class 12 sample papers. It is very helpful for exam point of view and you can get it from here.
