math script

Copy linkTweet thisAlerts:
Nov 28.2003

I need more help with a math script.
The function: a + b * x = y.
The teatcher enters for example a = 30 and b = 8.
The student can choose between 1-100 in the x field.
The script will compute the calculation and come up with an y answer.
The answer has to be hidden and the student has to figure out the y value.
When the calculation from the script matches the value the student has come up with the value is true or otherwise false and the student has to try again.
Thanks

&lt;script type="text/javascript"&gt;
function check()
{
var a = parseInt(document.f.a.value);
var b = parseInt(document.f.b.value);
var x = parseInt(document.f.x.value);
var y = parseInt(document.f.y.value);

if ( a + b * x == y ) alert("That's right!!!");
else
{
alert("No, try again");
document.f.y.focus();
}
}

&lt;/script&gt;
&lt;body&gt;
&lt;form name=f&gt;
&lt;table&gt;
&lt;tr&gt;
&lt;td&gt;&lt;input type=text name=a&gt;&lt;/td&gt;
&lt;td&gt;+&lt;/td&gt;
&lt;td&gt;&lt;input type=text name=b&gt;&lt;/td&gt;
&lt;td&gt;*&lt;/td&gt;
&lt;td&gt;&lt;input type=text name=x&gt;&lt;/td&gt;
&lt;td&gt;=&lt;/td&gt;
&lt;td&gt;&lt;input type=text name=y&gt;&lt;/td&gt;
&lt;td&gt;&lt;button onclick="check();"&gt;Check Answer&lt;/button&gt;
&lt;/tr&gt;
&lt;/table&gt;
&lt;/form&gt;
&lt;/body&gt;
