4 times 24 is 96, but what is the answer if both 4 and 24 are negative numbers? Here we will determine if the answer to negative 4 times negative 24 is positive 96 or negative 96.
There are many different ways to explain and determine if the answer to negative 4 times negative 24 is -96 or +96 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 -96 is the correct answer using basic algebra.
We will test if -96 is correct by setting up the equation negative 4 times negative 24 equals negative 96, and then simplifying the equation to see if it is true.
(-4) (-24) = (-96)
Divide both sides of the equation by (-24) :
|
| = |
|
The numerator and denominator on the left side both have (-24) which even each other out and can be removed:
| (-4) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-4) = |
|
A numerator of 96 and denominator of 24 on the right side is the same as 96 divided by 24 which is 4. Now we end up with this untrue equation:
(-4) = (4)
-4 is NOT equal to 4, thus we have proven that negative 4 times negative 24 is not equal to -96. The answer must therefore be 96:
-4 x -24 = 96
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 4 times negative 24 will always have a positive answer.
