32 times 91 is 2912, but what is the answer if both 32 and 91 are negative numbers? Here we will determine if the answer to negative 32 times negative 91 is positive 2912 or negative 2912.
There are many different ways to explain and determine if the answer to negative 32 times negative 91 is -2912 or +2912 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 -2912 is the correct answer using basic algebra.
We will test if -2912 is correct by setting up the equation negative 32 times negative 91 equals negative 2912, and then simplifying the equation to see if it is true.
(-32) (-91) = (-2912)
Divide both sides of the equation by (-91) :
|
| = |
|
The numerator and denominator on the left side both have (-91) which even each other out and can be removed:
| (-32) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-32) = |
|
A numerator of 2912 and denominator of 91 on the right side is the same as 2912 divided by 91 which is 32. Now we end up with this untrue equation:
(-32) = (32)
-32 is NOT equal to 32, thus we have proven that negative 32 times negative 91 is not equal to -2912. The answer must therefore be 2912:
-32 x -91 = 2912
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 32 times negative 91 will always have a positive answer.
