99 times 33 is 3267, but what is the answer if both 99 and 33 are negative numbers? Here we will determine if the answer to negative 99 times negative 33 is positive 3267 or negative 3267.
There are many different ways to explain and determine if the answer to negative 99 times negative 33 is -3267 or +3267 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 -3267 is the correct answer using basic algebra.
We will test if -3267 is correct by setting up the equation negative 99 times negative 33 equals negative 3267, and then simplifying the equation to see if it is true.
(-99) (-33) = (-3267)
Divide both sides of the equation by (-33) :
|
| = |
|
The numerator and denominator on the left side both have (-33) 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 3267 and denominator of 33 on the right side is the same as 3267 divided by 33 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 33 is not equal to -3267. The answer must therefore be 3267:
-99 x -33 = 3267
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 99 times negative 33 will always have a positive answer.
