    Addme : function(component) 
    {
        var A=Component.get("v.aval");
        var B=Component.get("v.bval");
        var C=a+b;
        console.log(c);
        Component.set("v.result",C);
    },
    Subme : function(component) 
    {
        var A=Component.get("v.aval");
        var B=Component.get("v.bval");
        var C=a-b;
        Component.set("v.result",C);
    },
     Mulme : function(component) 
    {
        var A=Component.get("v.aval");
        var B=Component.get("v.bval");
        var C=a*b;
        Component.set("v.result",c);
    }
   
})

Few things to be noted in your code that -

  1. spelling of onclick is wrong you can correct it

    <lightning:button label="Add" onclcik="{!c.Addme}"/>

  2. Component and component both are different as javascript is case sensitive language therefore it treats both variables different, so please make a sure correct case, lowercase, or uppercase for variables

  3. Try to use parseInt() javascript method to convert the values into numbers/integers, to be on a safer side.

Below is your code, which I try to make it error-free

Cmp File

<aura:component >
    
    <aura:attribute name="aval" type="Integer"/>
    <aura:attribute name="bval" type="Integer"/>
    <aura:attribute name="result" type="Integer"/>
    
    
    <lightning:card title="Calculator" iconName ="standard:lead">
        <aura:set attribute="actions">
            <lightning:buttonGroup>
                <lightning:button label="Add" onclick="{!c.Addme}"/>
                <lightning:button label="Subtract" onclick="{!c.Subme}" />
                <lightning:button label="multiply" onclick="{!c.Mulme}" />

            </lightning:buttonGroup>
        </aura:set> 
        
        
        <lightning:input label="enter the first NO" value="{!v.aval}"/>
        <lightning:input label="enter the second NO" value="{!v.bval}"/>
        <lightning:input label="result" value="{!v.result}"/>
        
   </lightning:card>
</aura:component>

JS File

({
    Addme : function(component) 
    {
        var A=component.get("v.aval");
        var B=component.get("v.bval");
        var C=parseInt(A)+parseInt(B);
        console.log(C);
        component.set("v.result",C);
    },
    Subme : function(component) 
    {
        var A=component.get("v.aval");
        var B=component.get("v.bval");
        var C=parseInt(A)-parseInt(B);
        component.set("v.result",C);
    },
     Mulme : function(component) 
    {
        var A=component.get("v.aval");
        var B=component.get("v.bval");
        var C=parseInt(A)*parseInt(B);
        component.set("v.result",C);
    }
   
})
