What is negative 80 times negative 95?




80 times 95 is 7600, but what is the answer if both 80 and 95 are negative numbers? Here we will determine if the answer to negative 80 times negative 95 is positive 7600 or negative 7600.

There are many different ways to explain and determine if the answer to negative 80 times negative 95 is -7600 or +7600 using mathematical terms such as additive inverse and mathematical laws like the Distribute Law.

We will take a different approach - process of elimination: We will simply test if -7600 is the correct answer using basic algebra.

We will test if -7600 is correct by setting up the equation negative 80 times negative 95 equals negative 7600, and then simplifying the equation to see if it is true.

(-80) (-95) = (-7600)

Divide both sides of the equation by (-95) :

   
(-80) (-95)
 
   
(-95)
 =
   
(-7600)
 
   
(-95)

The numerator and denominator on the left side both have (-95) which even each other out and can be removed:

  (-80) =
   
(-7600)
 
   
(-95)

The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:

  (-80) =
   
(7600)
 
   
(95)

A numerator of 7600 and denominator of 95 on the right side is the same as 7600 divided by 95 which is 80. Now we end up with this untrue equation:

(-80) = (80)

-80 is NOT equal to 80, thus we have proven that negative 80 times negative 95 is not equal to -7600. The answer must therefore be 7600:

-80 x -95 = 7600


The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 80 times negative 95 will always have a positive answer.
