53 times 63 is 3339, but what is the answer if both 53 and 63 are negative numbers? Here we will determine if the answer to negative 53 times negative 63 is positive 3339 or negative 3339.
There are many different ways to explain and determine if the answer to negative 53 times negative 63 is -3339 or +3339 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 -3339 is the correct answer using basic algebra.
We will test if -3339 is correct by setting up the equation negative 53 times negative 63 equals negative 3339, and then simplifying the equation to see if it is true.
(-53) (-63) = (-3339)
Divide both sides of the equation by (-63) :
|
| = |
|
The numerator and denominator on the left side both have (-63) which even each other out and can be removed:
| (-53) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-53) = |
|
A numerator of 3339 and denominator of 63 on the right side is the same as 3339 divided by 63 which is 53. Now we end up with this untrue equation:
(-53) = (53)
-53 is NOT equal to 53, thus we have proven that negative 53 times negative 63 is not equal to -3339. The answer must therefore be 3339:
-53 x -63 = 3339
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 53 times negative 63 will always have a positive answer.
