Answer 2

i dont knoe how to multiply negatives

Answer 3

Okay so just some rules
whenever you see a negative sign with a number think of it as a negative 1 is being multiplied with it. Like
-5 = -1x5 = -5
In the same way
-5 x 2 = -1 x 5 x 2 = -1 x 10 = -10
In the same way
-5 x -2 = -1 x 5 x -1 x 2 = -1 x -1 x 5 x 2 = 1 x 5 x 2 = 1 x 10 = 10

In a nutshell, negative multiplied negative will give positive number and negative multiplied by positive will give a negative number
