What is negative 4 times negative 53?




4 times 53 is 212, but what is the answer if both 4 and 53 are negative numbers? Here we will determine if the answer to negative 4 times negative 53 is positive 212 or negative 212.

There are many different ways to explain and determine if the answer to negative 4 times negative 53 is -212 or +212 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 -212 is the correct answer using basic algebra.

We will test if -212 is correct by setting up the equation negative 4 times negative 53 equals negative 212, and then simplifying the equation to see if it is true.

(-4) (-53) = (-212)

Divide both sides of the equation by (-53) :

   
(-4) (-53)
 
   
(-53)
 =
   
(-212)
 
   
(-53)

The numerator and denominator on the left side both have (-53) which even each other out and can be removed:

  (-4) =
   
(-212)
 
   
(-53)

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

  (-4) =
   
(212)
 
   
(53)

A numerator of 212 and denominator of 53 on the right side is the same as 212 divided by 53 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 53 is not equal to -212. The answer must therefore be 212:

-4 x -53 = 212


The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 4 times negative 53 will always have a positive answer.
