Which number is larger??

I sacrificed my sleeping time,

I sacrificed my dinner time,
I replaced my supper wit Indomee which take me only 15minutes to finish it,
(including the time to cook)

I'm trying to stay alert and focus.....
Just for the Maths test at 9am.

In the test paper,
one of the question required to choose a smaller number to proceed the steps.

choose among -1, -2.

I choose -1 is smaller than -2.

OMG!!!!!!

Hello brother, -2 is smaller than -1 !!!

I'm feeling ......
haih......
don't know how to express myself,
speechless....

what a stupid mistake I've done.....
