Foil Calculator is a free online tool developed to help you by displaying the simplification of the given expression. In the subject of Mathematics, the term FOIL stands for First, Outer, Inner, Last. It is a unique technique to distribute the binomials. 

Here, first means multiply the first terms which occur in the binomial function. Outer means multiplying the outermost terms of the binomial in the product. 

Inner represents multiplying the inner terms of the binomial. Finally, last means multiplying the last term in the binomial function. 

Once the process is finished, then you need to simplify the algebraic expression. 

For example, (x+1) and (x+2) are the two binomials. By using the FOIL method, it becomes:

(x+1) (x+2) = (x. x) + (x.2) + (1.x) + (1.2) and so on.

The procedure to use the foil calculator is as follows:

Step 1: Here, enter the expression in the input field.

Step 2: In the following step, you need to click the button “Calculate” to get the simplification.

Step 3: As a result, the simplified expression will be displayed in the output field.
