Without parseFloat, why it's still calculating.

var num1 = prompt("Give 1st number: ");

var ps1= parseFloat( num1 );

var num2 = prompt("Give 2nd number: ");

var ps2 = parseFloat( num2 );

document.write( num1 + " + " + num2 + " = " + (ps1 + ps2) + "<br>");

//==================Why ( num1 * num2 ) still getting calculated here?===

document.write( num1 + " * " + num2 + " = " + ( num1 * num2 ) + "<br>");

//==========================================================

document.write( num1 + " / " + num2 + " = " + ( ps1 / ps2 ) + "<br>");

document.write( num1 + " - " + num2 + " = " + ( ps1 - ps2 ) );

console.log("OK");

That's just the behavior and works for subtraction and division as well. From MDN. Addition is the only operator that behaves differently (concatenates) with strings.
