the condition are: if number 1 is less than number 2 result should be addition else if number 1 is greater than 2 result should be substraction else if number 1 is equal to number 2 result should be multiplication else if number 1 is divisible number 2 the result should be division.
javascript: calculate two numbers <script>

You need to name your function to call it like that
<button onclick="();">=</button> doesn't mean anything
function calculate()
{
var n1 = parseFloat(document.getElementById('n1').value);
var n2 = parseFloat(document.getElementById('n2').value);
console.log(n1, n2)
if(n1 > n2)
{
document.getElementById('result').value = n1+n2;
}
if(n1 < n2)
{
document.getElementById('result').value = n1-n2;
}
if(n1 == n2)
{
document.getElementById('result').value = n1/n2;
}
if(n1%2)
{
document.getElementById('result').value = n1*n2;
}
}<input type="text" id="n1"/><br/><br/>
