6 times 69 is 414, but what is the answer if both 6 and 69 are negative numbers? Here we will determine if the answer to negative 6 times negative 69 is positive 414 or negative 414.
There are many different ways to explain and determine if the answer to negative 6 times negative 69 is -414 or +414 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 -414 is the correct answer using basic algebra.
We will test if -414 is correct by setting up the equation negative 6 times negative 69 equals negative 414, and then simplifying the equation to see if it is true.
(-6) (-69) = (-414)
Divide both sides of the equation by (-69) :
| = |
|
The numerator and denominator on the left side both have (-69) 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 414 and denominator of 69 on the right side is the same as 414 divided by 69 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 69 is not equal to -414. The answer must therefore be 414:
-6 x -69 = 414
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 6 times negative 69 will always have a positive answer.
