Answer 2

<?php
$result = "";
class calculator
{
var $a;
var $b;

function checkopration($oprator)
{
switch($oprator)
{
case '+':
return $this->a + $this->b;
break;

case '-':
return $this->a - $this->b;
break;

case '*':
return $this->a * $this->b;
break;

case '/':
return $this->a / $this->b;
break;

default:
return "Sorry No command found";
}
}
function getresult($a, $b, $c)
{
$this->a = $a;
$this->b = $b;
return $this->checkopration($c);
}
}

$cal = new calculator();
if(isset($_POST['submit']))
{
$result = $cal->getresult($_POST['n1'],$_POST['n2'],$_POST['op']);
}
?>

<form method="post">
<table align="center">
<tr>
<td><strong><?php echo $result; ?><strong></td>
</tr>
<tr>
<td>Enter 1st Number</td>
<td><input type="text" name="n1"></td>
</tr>

# define functions
def add(x, y):
return x + y
def subtract(x, y):
return x - y
def multiply(x, y):
return x * y
def divide(x, y):
return x / y
# take input from the user
print("Select operation.")
print("1.Add")
print("2.Subtract")
print("3.Multiply")
print("4.Divide")
choice = input("Enter choice(1/2/3/4):")
num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
if choice == '1':
print(num1,"+",num2,"=", add(num1,num2))
elif choice == '2':
print(num1,"-",num2,"=", subtract(num1,num2))
elif choice == '3':
print(num1,"*",num2,"=", multiply(num1,num2))
elif choice == '4':
print(num1,"/",num2,"=", divide(num1,num2))
else:
print("Invalid input")

__________________________

you can do it like this

print("Select operation.")
print("1.Add")
print("2.Subtract")
print("3.Multiply")
print("4.Divide")
choice = input("Enter choice(1/2/3/4):")
num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
if choice == '1':
print(num1,"+",num2,"=", num1+num2)
elif choice == '2':
print(num1,"-",num2,"=", num1-num2)
elif choice == '3':
print(num1,"*",num2,"=", num1*num2)
elif choice == '4':
print(num1,"/",num2,"=", num1/num2)
else:
print("Invalid input")
