 # PHP Program to perform arithmetic operations

This program will help you to understand how to perform arithmetic operations in `PHP `programming.

For a better understanding of this example, we always recommend you to learn the basic topics of PHP programming listed below:

Arithmetic operations include

• Addition (+): Return the sum of the given digits
• Subtraction (-): Return the difference of the given digits
• Multiplication (*): Return the product of the given digits
• Division (/): Return the quotient of the given digits
• Modulo (%): Return the remainder of 1st digit divided by 2nd digit
• Exponentiation (**): Return the result of raising the 1st digit to the 2nd digit power.

## ALGORITHM

STEP 1: Declare two variables and assign values to them.

STEP 2: Perform the addition of two variables and display the result.

STEP 3: Perform the subtraction of two variables and display the result.

STEP 4: Perform the multiplication of two variables and display the result.

STEP 5: Perform the division of two variables and display the result.

STEP 6: Perform the modulo of two variables and display the result.

STEP 7: Perform the exponentiation of two variables and display the result.

## PHP Source Code

```                                          ``` <?php
\$x=20;
\$y=10;
\$z=\$x+\$y;
echo "Sum \$x+\$y = ",\$z, "<br>";
\$z=\$x-\$y;
echo "Difference \$x-\$y = ",\$z, "<br>";
\$z=\$x*\$y;
echo "Product \$x*\$y = ",\$z, "<br>";
\$z=\$x/\$y;
echo "Division \$x/\$y = ",\$z, "<br>";
\$y=15;
\$z=\$x%\$y;
echo "Modulo \$x%\$y = ",\$z, "<br>";
\$y=2;
\$z=\$x**\$y;
echo "Modulo \$x**\$y = ",\$z, "\n";
?> ```
```

## OUTPUT

```Sum 20+10 = 30
Difference 20-10 = 10
Product 20*10 = 200
Division 20/10 = 2
Modulo 20 = 5
Modulo 20**2 = 400```
