91 times 44 is 4004, but what is the answer if both 91 and 44 are negative numbers? Here we will determine if the answer to negative 91 times negative 44 is positive 4004 or negative 4004.
There are many different ways to explain and determine if the answer to negative 91 times negative 44 is -4004 or +4004 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 -4004 is the correct answer using basic algebra.
We will test if -4004 is correct by setting up the equation negative 91 times negative 44 equals negative 4004, and then simplifying the equation to see if it is true.
(-91) (-44) = (-4004)
Divide both sides of the equation by (-44) :
|
| = |
|
The numerator and denominator on the left side both have (-44) which even each other out and can be removed:
| (-91) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-91) = |
|
A numerator of 4004 and denominator of 44 on the right side is the same as 4004 divided by 44 which is 91. Now we end up with this untrue equation:
(-91) = (91)
-91 is NOT equal to 91, thus we have proven that negative 91 times negative 44 is not equal to -4004. The answer must therefore be 4004:
-91 x -44 = 4004
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 91 times negative 44 will always have a positive answer.
