26 times 10 is 260, but what is the answer if both 26 and 10 are negative numbers? Here we will determine if the answer to negative 26 times negative 10 is positive 260 or negative 260.
There are many different ways to explain and determine if the answer to negative 26 times negative 10 is -260 or +260 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 -260 is the correct answer using basic algebra.
We will test if -260 is correct by setting up the equation negative 26 times negative 10 equals negative 260, and then simplifying the equation to see if it is true.
(-26) (-10) = (-260)
Divide both sides of the equation by (-10) :
|
| = |
|
The numerator and denominator on the left side both have (-10) 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 260 and denominator of 10 on the right side is the same as 260 divided by 10 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 10 is not equal to -260. The answer must therefore be 260:
-26 x -10 = 260
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 26 times negative 10 will always have a positive answer.
