I have shown how you can perform math as well as logical operations together.

So first we will create a new windows application and design the below form.

Now use the below code,

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Example_of_math_variables_and_if_statements
{
public partial class Form1 : Form
{
private string x; //This defines the string variable x
private string y;
private string random_string;
private int x_number; //This defines the integer variable x_number
private int y_number;
private int random;
public Form1()
{
InitializeComponent(); //This creates the window from the information that was entered in the form designer
}
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
x = this.textBox1.Text;
y = this.textBox2.Text;
if (x == "") //This sees if x has no value
{
x = "0"; //This sets x to 0
}
if (y == "") //This sees if x has no value
{
y = "0"; //This sets y to 0
}
x_number = Convert.ToInt32(x); //This converts the string x to a integer then stores it in x_number
y_number = Convert.ToInt32(y);
random = x_number + y_number; //This sets the integer variable random to the value of x_number plus y_number
random_string = Convert.ToString(random); //This converts the integer random to the string random_string
this.label3.Text = random_string;
} //This method is called when the radiobutton (a button that when pressed makes every other radiobutton in its groupbox not pressed) is changed
private void radioButton2_CheckedChanged(object sender, EventArgs e)
{
x = this.textBox1.Text;
y = this.textBox2.Text;
if (x == "")
{
x = "0";
}
if (y == "")
{
y = "0";
}
x_number = Convert.ToInt32(x);
y_number = Convert.ToInt32(y);
random = x_number - y_number;
random_string = Convert.ToString(random);
this.label3.Text = random_string;
}
private void radioButton4_CheckedChanged(object sender, EventArgs e)
{

{

y_number = Convert.ToInt32(y);
if (y_number == 0) //This is to make sure that we don't divide by 0
{
random_string = "Divide by zero error";
}
else
{
random = x_number / y_number;
random_string = Convert.ToString(random);

this.label3.Text = random_string;
