6 times 79 is 474, but what is the answer if both 6 and 79 are negative numbers? Here we will determine if the answer to negative 6 times negative 79 is positive 474 or negative 474.
There are many different ways to explain and determine if the answer to negative 6 times negative 79 is -474 or +474 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 -474 is the correct answer using basic algebra.
We will test if -474 is correct by setting up the equation negative 6 times negative 79 equals negative 474, and then simplifying the equation to see if it is true.
(-6) (-79) = (-474)
Divide both sides of the equation by (-79) :
|
| = |
|
The numerator and denominator on the left side both have (-79) 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 474 and denominator of 79 on the right side is the same as 474 divided by 79 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 79 is not equal to -474. The answer must therefore be 474:
-6 x -79 = 474
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 6 times negative 79 will always have a positive answer.
