This might be too easy for people but I am confused so I need help
Why does 4(-20) equal -80?
I thought it equal just 80
Since í thought a positive times a negative would become a positive?
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 ?
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?
To understand why 4(-20) equals -80, let's break it down step by step.
In mathematics, the product of a positive number and a negative number is always negative. So, the sign of the final answer will depend on the signs of the numbers being multiplied.
Now, let's compute 4(-20) using the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Since there are no parentheses or exponents in this expression, we can focus on multiplication:
First, we multiply 4 by -20. The product of 4 and -20 is -80.
Therefore, 4(-20) is equal to -80, not 80.
To recap, when multiplying a positive number by a negative number, the result is always negative. In this case, the product of 4 and -20 is -80.
