76 times 6 is 456, but what is the answer if both 76 and 6 are negative numbers? Here we will determine if the answer to negative 76 times negative 6 is positive 456 or negative 456.
There are many different ways to explain and determine if the answer to negative 76 times negative 6 is -456 or +456 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 -456 is the correct answer using basic algebra.
We will test if -456 is correct by setting up the equation negative 76 times negative 6 equals negative 456, and then simplifying the equation to see if it is true.
(-76) (-6) = (-456)
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:
| (-76) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-76) = |
|
A numerator of 456 and denominator of 6 on the right side is the same as 456 divided by 6 which is 76. Now we end up with this untrue equation:
(-76) = (76)
-76 is NOT equal to 76, thus we have proven that negative 76 times negative 6 is not equal to -456. The answer must therefore be 456:
-76 x -6 = 456
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 76 times negative 6 will always have a positive answer.
