This might be too easy for people but I am confused so I need help

Question

Why does 4(-20) equal -80?

I thought it equal just 80
Since í thought a positive times a negative would become a positive?

Answer 1

no

(+)(+) ---> +
(+)(-) ---> -
(-)(+) ---> -
(-)(-) ---> +

back to your question

Suppose you had a debt of $20 or (-20)
if you quadrupled your debt , 4(-20)
would your debt not be $80 or -80 ?

Answer 2

Ohh thank you for understanding my problem because I was really confused!

The answer to your question is that my debt would not be $80.

Am í right?
