The asnwer is alway true because negative means reverse and positive makes the thing stay the ssame basically a positive is a blank thing that doesn't do anything while a negative makes change happen (opposite) with 1 blank thing and an opposite, we get an oposite
so we havve -7 times +11 we can factor out the -1 in -7 so we get -1 times 7 times 11 we know that 7 times 11=77 then the negative makes it oposite so -1
therefor if you have -x times +z that equals -1 times (x times z) and since x and z are both positive, they remain so, but the -1 makes it negative
