6 times 6 is 36, but what is the answer if both 6 and 6 are negative numbers? Here we will determine if the answer to negative 6 times negative 6 is positive 36 or negative 36.
There are many different ways to explain and determine if the answer to negative 6 times negative 6 is -36 or +36 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 -36 is the correct answer using basic algebra.
We will test if -36 is correct by setting up the equation negative 6 times negative 6 equals negative 36, and then simplifying the equation to see if it is true.
(-6) (-6) = (-36)
Divide both sides of the equation by (-6) :
|
| = |
|
The numerator and denominator on the left side both have (-6) which even each other out and can be removed:
| (-6) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-6) = |
|
A numerator of 36 and denominator of 6 on the right side is the same as 36 divided by 6 which is 6. Now we end up with this untrue equation:
(-6) = (6)
-6 is NOT equal to 6, thus we have proven that negative 6 times negative 6 is not equal to -36. The answer must therefore be 36:
-6 x -6 = 36
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 6 times negative 6 will always have a positive answer.
