(-19)(2)(37)(-0.8)(-112) Positive or Negative?

Answer 1

Hi there!

There are a few rules for multiplying positive and negative numbers:

-Any negative number times a negative number is a positive.
-Any positive number times a negative number is a negative.
-Any negative number times a positive number is a negative.
-Any positive number times a positive number is a positive.

So, using these rules, let's work through the multiplication:

-19 is a negative, and multiply by +2, would be a negative.
Multiply a negative by +37, and you still have a negative.
Multiply a negative by -0.8, and you will have a positive.
Multiply a positive with -112, and you will get a negative.

So, your answer would be a negative number.

Hope this helps!
