Answer 1

oh god i hate these. well -1 trough -13 don't work. both should be a negative. it should be both negative because negative times a negative = a positive. so unless your creative your ganna have to skip it and ask your teacher or something.

Nothing.

Factors of 16: 1, 2, 4, 8, 16

none of these numbers together can get -13.
