What is negative 4 times negative 26?




4 times 26 is 104, but what is the answer if both 4 and 26 are negative numbers? Here we will determine if the answer to negative 4 times negative 26 is positive 104 or negative 104.

There are many different ways to explain and determine if the answer to negative 4 times negative 26 is -104 or +104 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 -104 is the correct answer using basic algebra.

We will test if -104 is correct by setting up the equation negative 4 times negative 26 equals negative 104, and then simplifying the equation to see if it is true.

(-4) (-26) = (-104)

Divide both sides of the equation by (-26) :

   
(-4) (-26)
 
   
(-26)
 =
   
(-104)
 
   
(-26)

The numerator and denominator on the left side both have (-26) which even each other out and can be removed:

  (-4) =
   
(-104)
 
   
(-26)

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

  (-4) =
   
(104)
 
   
(26)

A numerator of 104 and denominator of 26 on the right side is the same as 104 divided by 26 which is 4. Now we end up with this untrue equation:

(-4) = (4)

-4 is NOT equal to 4, thus we have proven that negative 4 times negative 26 is not equal to -104. The answer must therefore be 104:

-4 x -26 = 104


The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 4 times negative 26 will always have a positive answer.
