Hello My fellow coders i am in desperate need of some help as im not sure how to address making a multiple choice game with randomly generated math equations. My current coding is not returning any answers or numbers even inside the console. Please help me out without telling me exactly how to do it. I would love some pointers and explanations:) So my original angle on how to do this is that there would be two randomly generated numbers using a Math.random object and multiplying it by 10 so that i get whole numbers from 0-10 that are in the equation then i want to display them inside the box marked question with an id tag. Thank you so much in advance! Right now i really need help on just getting the equation to pop up lmao and i would like the simplest code to do it I have only been doing javascript for 2 months now and havent quite gotten the hang of it yet! Also How might i go about reffering to the answer so that i can place it in a box later
Heres the html:
<head>
<title>Math Game</title>

<!--Because the score value is going to change as the user plays the game we need to place it in a span and refer to it later with some JAVA-->

<!--It is good practice to write the java at the end of the body element so all the divs load. Also use an external file for the javascript for clarity-->
<script src="Javascript.js"></script>
</body>
heres the javascript:
var gameOn = false;
var score;
var interval;
function stopGame() {
gameOn = false;
if (interval) {
clearInterval(interval);
interval = null;
}
document.getElementById("startreset").innerHTML = "Start Game";
document.getElementById("time-remaining").style.display = "";
}
//if we click on the start/reset
document.getElementById("startreset").onclick = function () {
//if we are not playing
if (gameOn) {
stopGame();
} else {
//change mode to playing
gameOn = true;
//set score to 0
score = 0;
document.getElementById("scorevalue").innerHTML = score;
//show countdown box
document.getElementById("time-remaining").style.display = "block";
document.getElementById("startreset").innerHTML = "Reset Game";
var counter = 60;
//reduce time by 1sec in loops
interval = setInterval(timeIt, 1000);
function timeIt(){
document.getElementById("timer-down").innerHTML = counter;
counter--;
//timeleft?
//no->gameover
if ( counter === 0) {
stopGame();
document.getElementById("game-over").style.display = "block";
}
}
//generate new Q&A
function generateQ(){
var a = Math.floor(Math.random()*10);
var b = Math.floor(Math.random()*10);
var result = +a + +b;
document.getElementById("firstInt").innerHTML = a;
document.getElementById("secondInt").innerHTML = b;
console.log(result);
}
}
}
}
