1 times 53 is 53, but what is the answer if both 1 and 53 are negative numbers? Here we will determine if the answer to negative 1 times negative 53 is positive 53 or negative 53.
There are many different ways to explain and determine if the answer to negative 1 times negative 53 is -53 or +53 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 -53 is the correct answer using basic algebra.
We will test if -53 is correct by setting up the equation negative 1 times negative 53 equals negative 53, and then simplifying the equation to see if it is true.
(-1) (-53) = (-53)
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:
| (-1) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-1) = |
|
A numerator of 53 and denominator of 53 on the right side is the same as 53 divided by 53 which is 1. Now we end up with this untrue equation:
(-1) = (1)
-1 is NOT equal to 1, thus we have proven that negative 1 times negative 53 is not equal to -53. The answer must therefore be 53:
-1 x -53 = 53
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 1 times negative 53 will always have a positive answer.
