92 times 4 is 368, but what is the answer if both 92 and 4 are negative numbers? Here we will determine if the answer to negative 92 times negative 4 is positive 368 or negative 368.
There are many different ways to explain and determine if the answer to negative 92 times negative 4 is -368 or +368 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 -368 is the correct answer using basic algebra.
We will test if -368 is correct by setting up the equation negative 92 times negative 4 equals negative 368, and then simplifying the equation to see if it is true.
(-92) (-4) = (-368)
Divide both sides of the equation by (-4) :
|
| = |
|
The numerator and denominator on the left side both have (-4) which even each other out and can be removed:
| (-92) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-92) = |
|
A numerator of 368 and denominator of 4 on the right side is the same as 368 divided by 4 which is 92. Now we end up with this untrue equation:
(-92) = (92)
-92 is NOT equal to 92, thus we have proven that negative 92 times negative 4 is not equal to -368. The answer must therefore be 368:
-92 x -4 = 368
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 92 times negative 4 will always have a positive answer.
