Why does my Log say the Value is NaN?

well, i have this part of my code inside the js now everytime the loop runs it's supposed to generate a random value for x , y , vX , vY and r but when I log the value inside the loop it says all those variables r NaN

this is the part

for(let i=0; i<100; i++){
  
  x = Math.random * innerWidth;
  y = Math.random * innerHeight;
  vX = Math.random * 10 - 5;
  vY = Math.random * 20 - 10;
  r = Math.random * 30;
  console.log(x);
  
  circleArray.push(new Circle(x,y,vX,vY,r));
  
}

for(let i=0; i<100; i++){
  
  x = Math.random * innerWidth;
  y = Math.random * innerHeight;
  vX = Math.random * 10 - 5;
  vY = Math.random * 20 - 10;
  r = Math.random * 30;
  console.log(x);
  
  circleArray.push(new Circle(x,y,vX,vY,r));
  
}

and this is the codepen
