6 times 51 is 306, but what is the answer if both 6 and 51 are negative numbers? Here we will determine if the answer to negative 6 times negative 51 is positive 306 or negative 306.
There are many different ways to explain and determine if the answer to negative 6 times negative 51 is -306 or +306 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 -306 is the correct answer using basic algebra.
We will test if -306 is correct by setting up the equation negative 6 times negative 51 equals negative 306, and then simplifying the equation to see if it is true.
(-6) (-51) = (-306)
Divide both sides of the equation by (-51) :
|
| = |
|
The numerator and denominator on the left side both have (-51) 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 306 and denominator of 51 on the right side is the same as 306 divided by 51 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 51 is not equal to -306. The answer must therefore be 306:
-6 x -51 = 306
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 6 times negative 51 will always have a positive answer.
