The calculator tool used for adding and subtracting the given rational expressions is called as the adding and subtracting rational expression calculator. The rational expression is the expression which has polynomial on both numerator or denominator or both. To add and subtract rational expressions the key point is to make the denominator the same expression.

Example 1: Find the answer for the expression 2x/5 + 12x/10 - 3x/5?

The given question is on adding and subtracting rational expression.

This question contains the adding and subtracting with same denominator 5 as 12x/10 = 6x/5.

The first step of the question is solving for 2x/5 + 6x/5 = 8x/5

Now subtract 3x/5 from the previous answer 8x/5

This makes the solution equal to 8x/5 - 3x/5 = 5x/5 = x

Example 2: Find the answer for the given expression 4x/6 + 5x/3 - x/3?

The given question is on adding and subtracting rational expression.

This question contains the adding and subtracting with same denominator 3

as 4x/6 = 2x/3.

The first step of the question is solving for 2x/3 + 5x/3 = 7x/3

Now subtract x/3 from the earlier answer 7x/3 = 6x/3 = 2x

This makes the solution equal to 4x/6 + 5x/3 - x/3 = 2x
