What is negative 56 times negative 43?




56 times 43 is 2408, but what is the answer if both 56 and 43 are negative numbers? Here we will determine if the answer to negative 56 times negative 43 is positive 2408 or negative 2408.

There are many different ways to explain and determine if the answer to negative 56 times negative 43 is -2408 or +2408 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 -2408 is the correct answer using basic algebra.

We will test if -2408 is correct by setting up the equation negative 56 times negative 43 equals negative 2408, and then simplifying the equation to see if it is true.

(-56) (-43) = (-2408)

Divide both sides of the equation by (-43) :

   
(-56) (-43)
 
   
(-43)
 =
   
(-2408)
 
   
(-43)

The numerator and denominator on the left side both have (-43) which even each other out and can be removed:

  (-56) =
   
(-2408)
 
   
(-43)

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

  (-56) =
   
(2408)
 
   
(43)

A numerator of 2408 and denominator of 43 on the right side is the same as 2408 divided by 43 which is 56. Now we end up with this untrue equation:

(-56) = (56)

-56 is NOT equal to 56, thus we have proven that negative 56 times negative 43 is not equal to -2408. The answer must therefore be 2408:

-56 x -43 = 2408


The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 56 times negative 43 will always have a positive answer.
