6 times 11 is 66, but what is the answer if both 6 and 11 are negative numbers? Here we will determine if the answer to negative 6 times negative 11 is positive 66 or negative 66.
There are many different ways to explain and determine if the answer to negative 6 times negative 11 is -66 or +66 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 -66 is the correct answer using basic algebra.
We will test if -66 is correct by setting up the equation negative 6 times negative 11 equals negative 66, and then simplifying the equation to see if it is true.
(-6) (-11) = (-66)
Divide both sides of the equation by (-11) :
|
| = |
|
The numerator and denominator on the left side both have (-11) 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 66 and denominator of 11 on the right side is the same as 66 divided by 11 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 11 is not equal to -66. The answer must therefore be 66:
-6 x -11 = 66
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 6 times negative 11 will always have a positive answer.
