24 times 6 is 144, but what is the answer if both 24 and 6 are negative numbers? Here we will determine if the answer to negative 24 times negative 6 is positive 144 or negative 144.
There are many different ways to explain and determine if the answer to negative 24 times negative 6 is -144 or +144 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 -144 is the correct answer using basic algebra.
We will test if -144 is correct by setting up the equation negative 24 times negative 6 equals negative 144, and then simplifying the equation to see if it is true.
(-24) (-6) = (-144)
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:
| (-24) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-24) = |
|
A numerator of 144 and denominator of 6 on the right side is the same as 144 divided by 6 which is 24. Now we end up with this untrue equation:
(-24) = (24)
-24 is NOT equal to 24, thus we have proven that negative 24 times negative 6 is not equal to -144. The answer must therefore be 144:
-24 x -6 = 144
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 24 times negative 6 will always have a positive answer.
