5 times 92 is 460, but what is the answer if both 5 and 92 are negative numbers? Here we will determine if the answer to negative 5 times negative 92 is positive 460 or negative 460.
There are many different ways to explain and determine if the answer to negative 5 times negative 92 is -460 or +460 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 -460 is the correct answer using basic algebra.
We will test if -460 is correct by setting up the equation negative 5 times negative 92 equals negative 460, and then simplifying the equation to see if it is true.
(-5) (-92) = (-460)
Divide both sides of the equation by (-92) :
|
| = |
|
The numerator and denominator on the left side both have (-92) which even each other out and can be removed:
| (-5) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-5) = |
|
A numerator of 460 and denominator of 92 on the right side is the same as 460 divided by 92 which is 5. Now we end up with this untrue equation:
(-5) = (5)
-5 is NOT equal to 5, thus we have proven that negative 5 times negative 92 is not equal to -460. The answer must therefore be 460:
-5 x -92 = 460
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 5 times negative 92 will always have a positive answer.
