How to Add and Subtract Negative Numbers?
Negative numbers can be easily added or subtracted performing addition and subtraction on negative numbers we must follow the following rules.
Addition of Negative Numbers
Addition of negative numbers is studied under two following headings:
- Case 1: Addition of two Negative Numbers
- Case 2: Addition of a Negative Number and a Positive Number
Now let’s learn the same in detail.
Case 1: Addition of two Negative Numbers
In the case of adding two negative numbers, we simply add the two numbers and then we put a negative (minus) sign in front of the result. This can be explained by following the example
Example: Simplify (-11) + (-7)
Solution:
= (-11) + (-7)
= -(11 + 7)
= -(18)
Case 2: Addition of a Negative Number and a Positive Number
In the case of the addition of a Negative Number and a Positive Number we simply find the difference of the two numbers and then put the sign of the bigger number. This can be explained by following the example,
Example: Simplify (-11) + 17
Solution:
= (-11) + 17
= (17 – 11)
= 6
Subtraction of Negative Numbers
Two negative numbers are subtracted by following the rule that says, “Change the operation of subtraction to addition and also change the sign of the second number.” This rule is explained by the example as,
Example: Simplify (-12) – (-14)
Solution:
(-12) – (-14)
= (-12) + 14
= (14 – 12)
= 2
Negative Numbers
Negative Numbers are the numbers that are represented on the negative side of the number line. Negative Numbers are the numbers whose value is less than zero. They are placed on the left-hand side of the zero on the number line. We apply the (-) minus sign before negative numbers to represent them. For example, -5 represents a number that is five units on the left side of zero in the number line.
In his article, we will learn about, negative numbers, operations on negative numbers, their properties, examples, and others in detail.
