I need help with this algebra problem

Question

I need help

I'm aweful at math and this is probably an easy problem but me nor my calculator could figure it out.

what is 15 • - 1

please help!

Answer 1

Neg 15.  A neg times a pos equals a neg.  A neg times a neg is pos and pos times pos is pos.  Hopefully this helps for future probs!  

Answer 2

15 • -1

'•' stands for multiplication (x).

So, 15x(-1)= -15.

If you are confused about the negative sign, you should know that negatives make no difference with the numbers but only with the signs.

- x -= +

+ x -= -

+ x += +

Answer 3

Fifteen times negative one equals negative fifteen.  You may have a +/- key on your calculator.

Answer 4

15 *-1=-15
