What is negative 46 times negative 8?




46 times 8 is 368, but what is the answer if both 46 and 8 are negative numbers? Here we will determine if the answer to negative 46 times negative 8 is positive 368 or negative 368.

There are many different ways to explain and determine if the answer to negative 46 times negative 8 is -368 or +368 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 -368 is the correct answer using basic algebra.

We will test if -368 is correct by setting up the equation negative 46 times negative 8 equals negative 368, and then simplifying the equation to see if it is true.

(-46) (-8) = (-368)

Divide both sides of the equation by (-8) :

   
(-46) (-8)
 
   
(-8)
 =
   
(-368)
 
   
(-8)

The numerator and denominator on the left side both have (-8) which even each other out and can be removed:

  (-46) =
   
(-368)
 
   
(-8)

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

  (-46) =
   
(368)
 
   
(8)

A numerator of 368 and denominator of 8 on the right side is the same as 368 divided by 8 which is 46. Now we end up with this untrue equation:

(-46) = (46)

-46 is NOT equal to 46, thus we have proven that negative 46 times negative 8 is not equal to -368. The answer must therefore be 368:

-46 x -8 = 368


The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 46 times negative 8 will always have a positive answer.
