muliptying integers and getting wrong answer for quiz
My question reads:
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.
I am stuck as to what it wants in the quiz.
<?php //Place your code below this comment $integerOne = 1; $integerTwo = 2; var_dump ($integerOne+=5); var_dump ($integerTwo-=1); /* 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.*/ $floatOne = 1.5; var_dump ($integerOne * $floatOne); ?>

You've got it almost correct... the main syntax the challenge is looking for is all correct.
However, HINT -> nowhere in any of the tasks' instructions does it ask you to use
Give it another go with that in mind.
Keep coding! :)

Hi Ali, you don't need the var_dump function - this is used to check what's inside a variable (usually when debugging) but not used to assign values or print them onto the page. You are getting an error because var_dump on those numbers checks the value but doesn't actually change the variable's value, and in the last line "echo" is the keyword you want to use to print out the value:
//Place your code below this comment $integerOne=1; $integerTwo=2; $integerOne+=5; $integerTwo-=1; $floatOne=1.5; echo $integerOne * $floatOne;
