Introduction There are different types of number system in mathematics. Like natural numbers, whole numbers, integers, rational numbers, etc. Integers are whole numbers which contains negative numbers, positive numbers and zero. For examples:
----------3, -2, -1, 0, 1, 2, 3, ----------- are integers.
Most of the students face the problem to solve integers and when fail, they develop maths phobia. In this article you will find a simple method to solve different operations with integers.
Addition and subtraction of integers It is very easy to solve addition and subtraction of integers. I am providing two simple rules to solve addition and subtraction of integers. If the sign of two numbers are same, apply the first rule and if the sign of two numbers are different then apply the second rule.
Rule No. 1 If the sign of the two numbers are same i.e. both numbers are positive or both numbers are negative , then add them without taking sign. After adding put the sign of greater number in the answer.
so, -6-21 =-27.
Rule No. 2 If the sign of two numbers are different then we will subtract the smaller number from the bigger number (as numeric). After that put the sign of bigger number in the answer. For examples:
Multiplication and division of integers Now we will learn to solve multiplication and division of integers. The multiplication and division of integers are same as simple multiply and division. We have to only learn to put sign in the answer. Two negatives become a positive number. To solve multiplication please remember:
For example you have to solve :
Same rule is applicable for the division of integers.
Last words So, it is very easy to solve operation with integers. You have learn the rules to solve different operations with integers. You can also visit my Youtube channel to learn: https://www.youtube.com/channel/UCpL_TFWI93bxxQYrTK3yjaA
