jQuery += a variable help

So I have 

VARIABLE = Math.floor(5*Math.random());

Then

.animate({left: '+=VARIABLE'}

but it doesn't work.

In my css my div already has a left attribute. If I do left: newx + 'px' it sends it to the random number I generated, meaning it jumps to the top of the page.

What do you mean by += a variable? You want to increase the current value of the left position? If so you can also fetch the raw number with the .offset() method, increase it, and use it as the new position.

Variables are not interpolated in strings. Try this:

.animate({left: '+='+VARIABLE}
