24 times 69 is 1656, but what is the answer if both 24 and 69 are negative numbers? Here we will determine if the answer to negative 24 times negative 69 is positive 1656 or negative 1656.
There are many different ways to explain and determine if the answer to negative 24 times negative 69 is -1656 or +1656 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 -1656 is the correct answer using basic algebra.
We will test if -1656 is correct by setting up the equation negative 24 times negative 69 equals negative 1656, and then simplifying the equation to see if it is true.
(-24) (-69) = (-1656)
Divide both sides of the equation by (-69) :
|
| = |
|
The numerator and denominator on the left side both have (-69) 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 1656 and denominator of 69 on the right side is the same as 1656 divided by 69 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 69 is not equal to -1656. The answer must therefore be 1656:
-24 x -69 = 1656
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 24 times negative 69 will always have a positive answer.
