So the initial code is var product = 2.0 * 0.0; and the challenge asks you to change the 0.0 so the variable product is 5. var product = 2.0 * 5; is not 5
that is not the solution - we don’t usually give solutions in the forum, as learning is done best reaching the solution on one own - but it is a really good hint
you should ask something if you have issues, there are no techno-telepaths here that we can guess what’s the answer you need
