Hi, my code works but i was wondering if it could be be shortened / made simpler?

alert("Let's do some math!"); 
var input1 = parseFloat(prompt("type a number")); 
var input2 = parseFloat(prompt("type another number")); 
document.write("<h1>Math with the numbers " + input1 + " and " + input2 + "</h1>"); 
addition(input1, input2);
multiplication(input1, input2);
division(input1, input2);
subtraction(input1, input2);

function addition (num1, num2) {
    var result = num1 + num2;
    printResult(num1, num2, "+", result);
}

function multiplication (num1, num2) {
    var result = num1 * num2;
    printResult(num1, num2, "*", result);
}

function subtraction (num1, num2) {
    var result = num1 - num2;
    printResult(num1, num2, "-", result);
}

function division (num1, num2) {
    var result = num1 / num2;
    printResult(num1, num2, "/", result);
}

function printResult(num1, num2, operationCharacter, result){
    document.write("<br>" + num1 + " " + operationCharacter + " " + num2 + " = " + result);
}
