What is negative 29 times negative 8?




29 times 8 is 232, but what is the answer if both 29 and 8 are negative numbers? Here we will determine if the answer to negative 29 times negative 8 is positive 232 or negative 232.

There are many different ways to explain and determine if the answer to negative 29 times negative 8 is -232 or +232 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 -232 is the correct answer using basic algebra.

We will test if -232 is correct by setting up the equation negative 29 times negative 8 equals negative 232, and then simplifying the equation to see if it is true.

(-29) (-8) = (-232)

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

   
(-29) (-8)
 
   
(-8)
 =
   
(-232)
 
   
(-8)

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

  (-29) =
   
(-232)
 
   
(-8)

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

  (-29) =
   
(232)
 
   
(8)

A numerator of 232 and denominator of 8 on the right side is the same as 232 divided by 8 which is 29. Now we end up with this untrue equation:

(-29) = (29)

-29 is NOT equal to 29, thus we have proven that negative 29 times negative 8 is not equal to -232. The answer must therefore be 232:

-29 x -8 = 232


The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 29 times negative 8 will always have a positive answer.
