Given: The  sum of a certain number and 3

To find The value of the above expression

Solution: In mathematics, there are four basic operations are there and they are multiplication, subtraction, addition, and division. The operation addition is performed when we want to add or combine two or more terms or numbers into a single form. This operation, we can implement in our daily lives. It is represented by the sign '+'.

The Sum is actually the result of the addition operation that we perform it various problems.

Let us consider a certain number to be 'p'.

∴ According to the question,

The sum of a certain number and 3 or the sum of p and 3 is equal to the (p+3).

As we are not aware of a certain number, we can take any variable to represent the same, this variable is taken as a reference to determine the required sum.

Hence the sum of a certain number 'p' and 3 is (p+3).
