What is negative 49 times negative 23? (-49 x -23)

What is negative 49 times negative 23?

49 times 23 is 1127, but what is the answer if both 49 and 23 are negative numbers? Here we will determine if the answer to negative 49 times negative 23 is positive 1127 or negative 1127.

There are many different ways to explain and determine if the answer to negative 49 times negative 23 is -1127 or +1127 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 -1127 is the correct answer using basic algebra.

We will test if -1127 is correct by setting up the equation negative 49 times negative 23 equals negative 1127, and then simplifying the equation to see if it is true.

(-49) (-23) = (-1127)

Divide both sides of the equation by (-23) :

		(-49) (-23)
		(-23)

		(-1127)
		(-23)

The numerator and denominator on the left side both have (-23) which even each other out and can be removed:

(-49) =

		(-1127)
		(-23)

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

(-49) =

		(1127)
		(23)

A numerator of 1127 and denominator of 23 on the right side is the same as 1127 divided by 23 which is 49. Now we end up with this untrue equation:

(-49) = (49)

-49 is NOT equal to 49, thus we have proven that negative 49 times negative 23 is not equal to -1127. The answer must therefore be 1127:

-49 x -23 = 1127

The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 49 times negative 23 will always have a positive answer.
