Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
1) is insufficient. if x = 2, and y = -2, X = |y|; if x = 3 and y = -2, x>|y|
2) is sufficient. If y <0 then x> -(y) because y <0 so x >|y|. An example. y = -13. This means that x > -(-13); x > 13, so x >|y|.

I misstated my reply to ndidi--
In ndidi's example, s/he uses the plug method, and he s/he states:
"if x = 2, and y = -2"
but that violates the parameters of the problem, which states that "x + y > 0". If you plug those numbers, you get 2+(-2)>0, which is untrue.
