Hey Rachel,

Try using Math.floor instead and see if it works better for you :)

Duh. Just realized. Wow. Thank you.

Question

Complete the following code so that the results of this math operation are rounded down to the nearest integer. For example, .6 will be rounded to 0.

To round down numbers in JS you need to use Math.floor() method.

The question says "rounded down to the NEAREST integer". Math.round() automatically rounds it to the nearest integer. Then the second part says that if it is 0.6 then it should be rounded to 0 in which case we should use Math.floor(). I think the question is not clear and need to be rephrased to remove the word "nearest", until then, Math.round() is a right answer.

The answer is: Math.floor( 5 / 2)

Math.floor(5 / 2) ;
