# About

All operations in the program are visual on one page.

Arithmetical expressions must be written in one line using the following characters: 0, 1, 2, 3 …for numbers, and

**+ addition, – subtraction, * multiplication, / division, ( ) parentheses.**

The program checks the arithmetic expression.

In the program, you can add, subtract, multiply and divide integers into columns, decompose a number into prime factors in different ways. For the time being we offer a short version of the program without division operations. The program provides:

**an independent solution, a software solution, a joint solution.**

In addition, each option can be changed at any stage.

Because the program uses the entire screen, we recommend using a separate table that can be easily created with the buttons

**tab+win.**

The main idea of the program is to use a simple text editor to calculate an arithmetic expression.

To do this, use the / and (, ) buttons to write the fractional part.

Also at any stage of the solution of a complex arithmetic expression, one can perform the operations of addition, subtraction, multiplication and division of numbers in a special editor.

The basic theorem of arithmetic on the representation of any number in the form of a product of prime numbers can be solved here separately, when it is necessary to add fractions with different denominators.

The entire stage of solving a complex arithmetic expression is done visually on one page of the screen.

We can write the new variant of arithmetic expression in a simple text editor. The program checks the equality.

We can go this way until we get the result.

We have a choice to transfer control to the program at each stage of solving the expression.

The program can solve expressions independently displaying the result on the screen and can continue the solution together with you.
