What is negative 47 times negative 50? (-47 x -50)

What is negative 47 times negative 50?

47 times 50 is 2350, but what is the answer if both 47 and 50 are negative numbers? Here we will determine if the answer to negative 47 times negative 50 is positive 2350 or negative 2350.

There are many different ways to explain and determine if the answer to negative 47 times negative 50 is -2350 or +2350 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 -2350 is the correct answer using basic algebra.

We will test if -2350 is correct by setting up the equation negative 47 times negative 50 equals negative 2350, and then simplifying the equation to see if it is true.

(-47) (-50) = (-2350)

Divide both sides of the equation by (-50) :

		(-47) (-50)
		(-50)

		(-2350)
		(-50)

The numerator and denominator on the left side both have (-50) which even each other out and can be removed:

(-47) =

		(-2350)
		(-50)

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

(-47) =

		(2350)
		(50)

A numerator of 2350 and denominator of 50 on the right side is the same as 2350 divided by 50 which is 47. Now we end up with this untrue equation:

(-47) = (47)

-47 is NOT equal to 47, thus we have proven that negative 47 times negative 50 is not equal to -2350. The answer must therefore be 2350:

-47 x -50 = 2350

The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 47 times negative 50 will always have a positive answer.
