27 times 53 is 1431, but what is the answer if both 27 and 53 are negative numbers? Here we will determine if the answer to negative 27 times negative 53 is positive 1431 or negative 1431.
There are many different ways to explain and determine if the answer to negative 27 times negative 53 is -1431 or +1431 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 -1431 is the correct answer using basic algebra.
We will test if -1431 is correct by setting up the equation negative 27 times negative 53 equals negative 1431, and then simplifying the equation to see if it is true.
(-27) (-53) = (-1431)
Divide both sides of the equation by (-53) :
|
| = |
|
The numerator and denominator on the left side both have (-53) which even each other out and can be removed:
| (-27) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-27) = |
|
A numerator of 1431 and denominator of 53 on the right side is the same as 1431 divided by 53 which is 27. Now we end up with this untrue equation:
(-27) = (27)
-27 is NOT equal to 27, thus we have proven that negative 27 times negative 53 is not equal to -1431. The answer must therefore be 1431:
-27 x -53 = 1431
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 27 times negative 53 will always have a positive answer.
