What is negative 64 times negative 82?

64 times 82 is 5248, but what is the answer if both 64 and 82 are negative numbers? Here we will determine if the answer to negative 64 times negative 82 is positive 5248 or negative 5248.

There are many different ways to explain and determine if the answer to negative 64 times negative 82 is -5248 or +5248 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 -5248 is the correct answer using basic algebra.

We will test if -5248 is correct by setting up the equation negative 64 times negative 82 equals negative 5248, and then simplifying the equation to see if it is true.

(-64) (-82) = (-5248)

Divide both sides of the equation by (-82) :

		(-64) (-82)
		(-82)

		(-5248)
		(-82)

The numerator and denominator on the left side both have (-82) which even each other out and can be removed:

(-64) =

		(-5248)
		(-82)

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

(-64) =

		(5248)
		(82)

A numerator of 5248 and denominator of 82 on the right side is the same as 5248 divided by 82 which is 64. Now we end up with this untrue equation:

(-64) = (64)

-64 is NOT equal to 64, thus we have proven that negative 64 times negative 82 is not equal to -5248. The answer must therefore be 5248:

-64 x -82 = 5248

The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 64 times negative 82 will always have a positive answer.
