"Using JavaScript Controllers with Components" Lightining Trailhead Challenge - Need Help

Hello , I was trying to complete all challenge about lightining, i was able to pass all of them except "Using Javascript Controller with Components" challenge. I was not able to figure out why trailhead gives the  error below  :

Here is my component :

 

<aura:component > 
    <ui:inputNumber aura:id="inputOne" onError='{!c.handleError}' /> <br />
    <ui:inputNumber aura:id="inputTwo" onError='{!c.handleError}' /> <br/> 
    <ui:inputNumber aura:id="inputThree" onError='{!c.handleError}' /> <br/>
    <ui:outputNumber aura:id="totalValue" value="" /><br/>
	 <ui:button label="Calculate"  press="{!c.calculate}"/>  
</aura:component>

and here is my js controler :

 

({
	calculate : function(component, event, helper) {
		var inputFirst = component.find("inputOne").get("v.value");
        var inputSecond = component.find("inputTwo").get("v.value");
        var inputThird = component.find("inputThree").get("v.value");
        var total = parseInt(inputFirst) + parseInt(inputSecond) - parseInt(inputThird);
        component.find("totalValue").set("v.value",total);
	}
})

Thanks.

    Meybe I found the reason:

    Line 6:

    var total = parseInt(inputFirst) + parseInt(inputSecond) - parseInt(inputThird);

    Replace with (It must be sum):

    var total = parseInt(inputFirst) + parseInt(inputSecond) + parseInt(inputThird);
