# operators

how do i multiply a float by an integer which has already been applied an arithmetic operator to get challenge three right

index.php
```<?php

//Place your code below this comment
\$integerOne = 1;
\$integerTwo = 2;

var_dump (\$integerOne + 5);

\$integerTwo = --\$integerTwo;
var_dump (\$integerTwo);

\$floatOne = 1.5;
var_dump (\$integerOne * \$floatOne);
?>
``` Hi Kumbirai Ruth Huni,

Well if you are trying to pass this challenge you shouldn't use var_dump() function it's ussually for testing purposes. For the first task you have done well, You have assign values to \$integerOne and \$integerTwo

```<?php

//Place your code below this comment

// Assigned values to variable \$integerOne and \$integerTwo
\$integerOne = 1;
\$integerTwo = 2;
?>
```

For the Task 2 it asks to Add 5 to \$integerOne. Subtract 1 from \$integerTwo. Which is something like this.

```<?php

//Place your code below this comment

// Assigned values to variable \$integerOne and \$integerTwo
\$integerOne = 1;
\$integerTwo = 2;

\$integerOne += 5;

// Subtract 1 from \$integerTwo
\$integerTwo -= 1;
?>
```

And lastly Task 3 asks us to Create a New Float Variable named \$floatOne with a value of 1.5. Without changing the value of \$integerOne or \$floatOne, multiply \$integerOne by \$floatOne and display the results. Which is something like this.

```<?php

//Place your code below this comment

// Assigned values to variable \$integerOne and \$integerTwo
\$integerOne = 1;
\$integerTwo = 2;

\$integerOne += 5;

// Subtract 1 from \$integerTwo
\$integerTwo -= 1;

// New float varaible \$floatOne with a value of 1.5
\$floatOne = 1.5;

// Without changing the value of \$integerOne or \$floatOne, multiply \$integerOne by \$floatOne and display the results
echo \$integerOne * \$floatOne;

// You can check your displayed value by pressing "Preview" button which is in right top corner next to "Check Work" and "Get Help"
// Because you are using "echo" command you can actually see results in preview.
?>
```

I hope this helps you to better understand this challenge.
