Question 877469
It doesn't seem like they are referring to a previous problem.


Also I am not sure what your notation [x] is. I have occasionally seen [x] to be the floor value of x, in which [-77.99] = -78 and [3.5] = 3, but *[tex \large \lfloor -77.99 \rfloor] is better notation. Btw, you can use >= or \le ( *[tex \large \le ]) for less than or equal.
