# Arithmetic Operations on two numbers

Introduction:

Adding, subtraction, multiplication and division of two numbers with the help of two TextBoxes and result will  display in third TextBox by using window form.

Step 1: Open visual studio--> file menu-->new--> project--> then

Step 2: Take 3 TextBoxes one for input First number, other for second number and third one is for the result TextBox. Design the form as follows:

Step 3: Coding

using
System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Arithmetic
{
public partial class ArthOperations : Form
{
public ArthOperations()
{
InitializeComponent();
textBox3.Enabled = false;
}
private void add(object sender, EventArgs e)
{
float first;
float second;
float output;
first = Convert.ToInt32(textBox1.Text);
second = Convert.ToInt32(textBox2.Text);
output = first + second;
textBox3.Text=(output.ToString());
}

private void sub(object sender, EventArgs e)
{
float first;
float second;
float output;
first = Convert.ToInt32(textBox1.Text);
second = Convert.ToInt32(textBox2.Text);
output = first - second;
textBox3.Text = (output.ToString());
}

private void div(object sender, EventArgs e)
{
float first;
float second;
float output;
first = Convert.ToInt32(textBox1.Text);
second = Convert.ToInt32(textBox2.Text);
output = first / second;
textBox3.Text = (output.ToString());
}

private void mul(object sender, EventArgs e)     {
float first;
float second;
float output;
first = Convert.ToInt32(textBox1.Text);
second = Convert.ToInt32(textBox2.Text);
output = first * second;
textBox3.Text = (output.ToString());
}

private void clear(object sender, EventArgs e)
{
textBox1.Text = "";
textBox2.Text = "";
textBox3.Text = ""

}
}
}
