14 times 58 is 812, but what is the answer if both 14 and 58 are negative numbers? Here we will determine if the answer to negative 14 times negative 58 is positive 812 or negative 812.
There are many different ways to explain and determine if the answer to negative 14 times negative 58 is -812 or +812 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 -812 is the correct answer using basic algebra.
We will test if -812 is correct by setting up the equation negative 14 times negative 58 equals negative 812, and then simplifying the equation to see if it is true.
(-14) (-58) = (-812)
Divide both sides of the equation by (-58) :
|
| = |
|
The numerator and denominator on the left side both have (-58) which even each other out and can be removed:
| (-14) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-14) = |
|
A numerator of 812 and denominator of 58 on the right side is the same as 812 divided by 58 which is 14. Now we end up with this untrue equation:
(-14) = (14)
-14 is NOT equal to 14, thus we have proven that negative 14 times negative 58 is not equal to -812. The answer must therefore be 812:
-14 x -58 = 812
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 14 times negative 58 will always have a positive answer.
