Answer 2

Answer:

The value of  $(a+b)-(a-b)$ is $2b$.

Step-by-step explanation:

Given : The given expression is, $(a+b)-(a-b)$

We have to find the solution of this given expression.

Solution :

• The given expression is, $(a+b)-(a-b)$.
• Subtraction is one of the important arithmetic operation among division, multiplication,addition and subtraction in mathematics.
• With the help of subtraction, we can find the difference between two quantities.

• One thing to be noted that, to do subtraction of two terms, their variables and their powers should be equal.
• The given expression is,

      $(a+b)-(a-b)$ $= a+b-a+b$     (∵ $'-*+=-' and '-*-=+'$)

                            $=2b$         ($-a+a=0$)

• ∴ The value of  $(a+b)-(a-b)$ is $2b$.
