I am working on a JavaScript problem,where i am taking 5 inputs from user and calculating the average and displaying it with the associated grade the user has obtained.My program is working fine,but it prints the average and grade on a new blank page instead of the same.I tried different things,but didn't work.Basically,i need my program to print on same page instead of new one.

<form>
Exam 1:<br>
<input type="text" id ="Exam1"><br>
Exam 2:<br>
<input type="text" id="Exam2"><br>
Exam 3:<br>
<input type="text" id="Exam3"><br>
Exam 4:<br>
<input type="text" id="Exam4"><br>
Exam 5:<br>
<input type="text" id="Exam5"><br>

</form>
  
<button id="averageButton">Calculate</button>

   <script type"text/javascript">
  
  
   function average(a,b,c,d,e){
       return (a*1+b*1+c*1+d*1+e*1)/5;
   }
  
   document.getElementById("averageButton").onclick = function(){


       var a=parseInt(document.getElementById("Exam1").value);
var b=parseInt(document.getElementById("Exam2").value);
       var c=parseInt(document.getElementById("Exam3").value);
var d=parseInt(document.getElementById("Exam4").value);
       var e=parseInt(document.getElementById("Exam5").value);
      
document.write("Average: " + average(a,b,c,d,e)+ "<br>");
       if (average(a,b,c,d,e) >= 90) {
           document.write("Grade : A");
       } else if (average(a,b,c,d,e) >= 80) {
           document.write("Grade : B");
       } else if (average(a,b,c,d,e) >= 70) {
document.write("Grade : C");
       }else if (average(a,b,c,d,e) >= 60) {
document.write("Grade : D");
       } else {
document.write("Grade : F");
      
       }

}

We create two <p> tags after the button and use them to show the average and grade.

Exam 5:<br>

<input type="text" id="Exam5"><br>

<button id="averageButton">Calculate</button>

<p id="average"></p>

<p id="grade"></p>

<script type"text/javascript">

function average(a,b,c,d,e){

return (a*1+b*1+c*1+d*1+e*1)/5;

}

document.getElementById("averageButton").onclick = function(){


var a=parseInt(document.getElementById("Exam1").value);

var b=parseInt(document.getElementById("Exam2").value);

var c=parseInt(document.getElementById("Exam3").value);

var d=parseInt(document.getElementById("Exam4").value);

var e=parseInt(document.getElementById("Exam5").value);

document.getElementById("average").innerHTML="Average: " + average(a,b,c,d,e);

if (average(a,b,c,d,e) >= 90) {

document.getElementById("grade").innerHTML="Grade : A";

} else if (average(a,b,c,d,e) >= 80) {

document.getElementById("grade").innerHTML="Grade : B";

} else if (average(a,b,c,d,e) >= 70) {

document.getElementById("grade").innerHTML="Grade : C";

}else if (average(a,b,c,d,e) >= 60) {

document.getElementById("grade").innerHTML="Grade : D";
