Adding and Subtracting Real Numbers

Introduction :

Let us discuss about the adding and subtracting real numbers. The real number is declare the positive number, negative number, whole number, decimal number, large number, small number. The real number do not used the imaginary number. The example of the real number is 8, -4, 2.36, 789 and etc. The general notation of the real number is R. Next we see the adding and subtracting of the real numbers.

Adding and Subtracting Real Number

Adding real numbers

The adding the real number is used the two operands and one operator. The operands are positive or negative number. The operator of adding real number is ‘+’. The example is 4.83 +1 = 5.83.

The 4.83 and 1 is the operands of adding real number.
The + is the operator of adding real number.
Subtracting real numbers

The subtracting the real number is used the two operands and one operator. The operands are positive or decimal number. The operator of subtracting real number is ‘-’. The example is 3.14 - 2.

The 3.14 and 2 is the operands of subtracting real number.
The - is the operator of subtracting real number.


Example of Adding and Subtracting Real Numbers

The example of the adding real number is

Problem 1:

Find the 88.3 + (-41)

Solution

= 88 .3 + (-41)

= 47.3

Answer of the adding real number is 47.3

Problem 2:

Find the (-52) + (-38)

Solution

= (-52) + (-38)

= -90

Answer of the adding real number is -90

Example problem of subtracting real number

Problem 1:

Find the (-96) - 197

Solution

= (-96) - 197

= -293

Answer of the subtracting real number is 101

Problem 2:

Find the 124 – (-87)

Solution

= 124 – (-87)

= 211

Answer of the subtracting real number is 211
