16 times 14 is 224, but what is the answer if both 16 and 14 are negative numbers? Here we will determine if the answer to negative 16 times negative 14 is positive 224 or negative 224.
There are many different ways to explain and determine if the answer to negative 16 times negative 14 is -224 or +224 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 -224 is the correct answer using basic algebra.
We will test if -224 is correct by setting up the equation negative 16 times negative 14 equals negative 224, and then simplifying the equation to see if it is true.
(-16) (-14) = (-224)
Divide both sides of the equation by (-14) :
|
| = |
|
The numerator and denominator on the left side both have (-14) which even each other out and can be removed:
| (-16) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-16) = |
|
A numerator of 224 and denominator of 14 on the right side is the same as 224 divided by 14 which is 16. Now we end up with this untrue equation:
(-16) = (16)
-16 is NOT equal to 16, thus we have proven that negative 16 times negative 14 is not equal to -224. The answer must therefore be 224:
-16 x -14 = 224
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 16 times negative 14 will always have a positive answer.
