26 times 1 is 26, but what is the answer if both 26 and 1 are negative numbers? Here we will determine if the answer to negative 26 times negative 1 is positive 26 or negative 26.
There are many different ways to explain and determine if the answer to negative 26 times negative 1 is -26 or +26 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 -26 is the correct answer using basic algebra.
We will test if -26 is correct by setting up the equation negative 26 times negative 1 equals negative 26, and then simplifying the equation to see if it is true.
(-26) (-1) = (-26)
Divide both sides of the equation by (-1) :
|
| = |
|
The numerator and denominator on the left side both have (-1) which even each other out and can be removed:
| (-26) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-26) = |
|
A numerator of 26 and denominator of 1 on the right side is the same as 26 divided by 1 which is 26. Now we end up with this untrue equation:
(-26) = (26)
-26 is NOT equal to 26, thus we have proven that negative 26 times negative 1 is not equal to -26. The answer must therefore be 26:
-26 x -1 = 26
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 26 times negative 1 will always have a positive answer.
