99 times 92 is 9108, but what is the answer if both 99 and 92 are negative numbers? Here we will determine if the answer to negative 99 times negative 92 is positive 9108 or negative 9108.
There are many different ways to explain and determine if the answer to negative 99 times negative 92 is -9108 or +9108 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 -9108 is the correct answer using basic algebra.
We will test if -9108 is correct by setting up the equation negative 99 times negative 92 equals negative 9108, and then simplifying the equation to see if it is true.
(-99) (-92) = (-9108)
Divide both sides of the equation by (-92) :
|
| = |
|
The numerator and denominator on the left side both have (-92) which even each other out and can be removed:
| (-99) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-99) = |
|
A numerator of 9108 and denominator of 92 on the right side is the same as 9108 divided by 92 which is 99. Now we end up with this untrue equation:
(-99) = (99)
-99 is NOT equal to 99, thus we have proven that negative 99 times negative 92 is not equal to -9108. The answer must therefore be 9108:
-99 x -92 = 9108
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 99 times negative 92 will always have a positive answer.
