OpenStudy (anonymous):

virtually* sorry. It's as simple as that
OpenStudy (anonymous):
so for example if i had 18.4 – (- 18.9) it would really be 18.9+18.4
OpenStudy (anonymous):
yes, a double negative turns positive
OpenStudy (anonymous):
does it work that way all the time even in multiplication?
OpenStudy (anonymous):
depends on the equation, however though lets say its the same problems but multiplication, (18.4(-18.9)) then this would become -347.76
