What is negative 53 times negative 73?




53 times 73 is 3869, but what is the answer if both 53 and 73 are negative numbers? Here we will determine if the answer to negative 53 times negative 73 is positive 3869 or negative 3869.

There are many different ways to explain and determine if the answer to negative 53 times negative 73 is -3869 or +3869 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 -3869 is the correct answer using basic algebra.

We will test if -3869 is correct by setting up the equation negative 53 times negative 73 equals negative 3869, and then simplifying the equation to see if it is true.

(-53) (-73) = (-3869)

Divide both sides of the equation by (-73) :

   
(-53) (-73)
 
   
(-73)
 =
   
(-3869)
 
   
(-73)

The numerator and denominator on the left side both have (-73) which even each other out and can be removed:

  (-53) =
   
(-3869)
 
   
(-73)

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

  (-53) =
   
(3869)
 
   
(73)

A numerator of 3869 and denominator of 73 on the right side is the same as 3869 divided by 73 which is 53. Now we end up with this untrue equation:

(-53) = (53)

-53 is NOT equal to 53, thus we have proven that negative 53 times negative 73 is not equal to -3869. The answer must therefore be 3869:

-53 x -73 = 3869


The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 53 times negative 73 will always have a positive answer.
