What is negative 8 times negative 22?




8 times 22 is 176, but what is the answer if both 8 and 22 are negative numbers? Here we will determine if the answer to negative 8 times negative 22 is positive 176 or negative 176.

There are many different ways to explain and determine if the answer to negative 8 times negative 22 is -176 or +176 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 -176 is the correct answer using basic algebra.

We will test if -176 is correct by setting up the equation negative 8 times negative 22 equals negative 176, and then simplifying the equation to see if it is true.

(-8) (-22) = (-176)

Divide both sides of the equation by (-22) :

   
(-8) (-22)
 
   
(-22)
 =
   
(-176)
 
   
(-22)

The numerator and denominator on the left side both have (-22) which even each other out and can be removed:

  (-8) =
   
(-176)
 
   
(-22)

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

  (-8) =
   
(176)
 
   
(22)

A numerator of 176 and denominator of 22 on the right side is the same as 176 divided by 22 which is 8. Now we end up with this untrue equation:

(-8) = (8)

-8 is NOT equal to 8, thus we have proven that negative 8 times negative 22 is not equal to -176. The answer must therefore be 176:

-8 x -22 = 176


The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 8 times negative 22 will always have a positive answer.
