24 times 34 is 816, but what is the answer if both 24 and 34 are negative numbers? Here we will determine if the answer to negative 24 times negative 34 is positive 816 or negative 816.
There are many different ways to explain and determine if the answer to negative 24 times negative 34 is -816 or +816 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 -816 is the correct answer using basic algebra.
We will test if -816 is correct by setting up the equation negative 24 times negative 34 equals negative 816, and then simplifying the equation to see if it is true.
(-24) (-34) = (-816)
Divide both sides of the equation by (-34) :
|
| = |
|
The numerator and denominator on the left side both have (-34) which even each other out and can be removed:
| (-24) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-24) = |
|
A numerator of 816 and denominator of 34 on the right side is the same as 816 divided by 34 which is 24. Now we end up with this untrue equation:
(-24) = (24)
-24 is NOT equal to 24, thus we have proven that negative 24 times negative 34 is not equal to -816. The answer must therefore be 816:
-24 x -34 = 816
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 24 times negative 34 will always have a positive answer.
