9 times 52 is 468, but what is the answer if both 9 and 52 are negative numbers? Here we will determine if the answer to negative 9 times negative 52 is positive 468 or negative 468.
There are many different ways to explain and determine if the answer to negative 9 times negative 52 is -468 or +468 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 -468 is the correct answer using basic algebra.
We will test if -468 is correct by setting up the equation negative 9 times negative 52 equals negative 468, and then simplifying the equation to see if it is true.
(-9) (-52) = (-468)
Divide both sides of the equation by (-52) :
|
| = |
|
The numerator and denominator on the left side both have (-52) which even each other out and can be removed:
| (-9) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-9) = |
|
A numerator of 468 and denominator of 52 on the right side is the same as 468 divided by 52 which is 9. Now we end up with this untrue equation:
(-9) = (9)
-9 is NOT equal to 9, thus we have proven that negative 9 times negative 52 is not equal to -468. The answer must therefore be 468:
-9 x -52 = 468
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 9 times negative 52 will always have a positive answer.
