7 times 52 is 364, but what is the answer if both 7 and 52 are negative numbers? Here we will determine if the answer to negative 7 times negative 52 is positive 364 or negative 364.
There are many different ways to explain and determine if the answer to negative 7 times negative 52 is -364 or +364 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 -364 is the correct answer using basic algebra.
We will test if -364 is correct by setting up the equation negative 7 times negative 52 equals negative 364, and then simplifying the equation to see if it is true.
(-7) (-52) = (-364)
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:
| (-7) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-7) = |
|
A numerator of 364 and denominator of 52 on the right side is the same as 364 divided by 52 which is 7. Now we end up with this untrue equation:
(-7) = (7)
-7 is NOT equal to 7, thus we have proven that negative 7 times negative 52 is not equal to -364. The answer must therefore be 364:
-7 x -52 = 364
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 7 times negative 52 will always have a positive answer.
