What is negative 2 times negative 76?




2 times 76 is 152, but what is the answer if both 2 and 76 are negative numbers? Here we will determine if the answer to negative 2 times negative 76 is positive 152 or negative 152.

There are many different ways to explain and determine if the answer to negative 2 times negative 76 is -152 or +152 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 -152 is the correct answer using basic algebra.

We will test if -152 is correct by setting up the equation negative 2 times negative 76 equals negative 152, and then simplifying the equation to see if it is true.

(-2) (-76) = (-152)

Divide both sides of the equation by (-76) :

   
(-2) (-76)
 
   
(-76)
 =
   
(-152)
 
   
(-76)

The numerator and denominator on the left side both have (-76) which even each other out and can be removed:

  (-2) =
   
(-152)
 
   
(-76)

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

  (-2) =
   
(152)
 
   
(76)

A numerator of 152 and denominator of 76 on the right side is the same as 152 divided by 76 which is 2. Now we end up with this untrue equation:

(-2) = (2)

-2 is NOT equal to 2, thus we have proven that negative 2 times negative 76 is not equal to -152. The answer must therefore be 152:

-2 x -76 = 152


The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 2 times negative 76 will always have a positive answer.
