11 times 4 is 44, but what is the answer if both 11 and 4 are negative numbers? Here we will determine if the answer to negative 11 times negative 4 is positive 44 or negative 44.
There are many different ways to explain and determine if the answer to negative 11 times negative 4 is -44 or +44 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 -44 is the correct answer using basic algebra.
We will test if -44 is correct by setting up the equation negative 11 times negative 4 equals negative 44, and then simplifying the equation to see if it is true.
(-11) (-4) = (-44)
Divide both sides of the equation by (-4) :
|
| = |
|
The numerator and denominator on the left side both have (-4) which even each other out and can be removed:
| (-11) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-11) = |
|
A numerator of 44 and denominator of 4 on the right side is the same as 44 divided by 4 which is 11. Now we end up with this untrue equation:
(-11) = (11)
-11 is NOT equal to 11, thus we have proven that negative 11 times negative 4 is not equal to -44. The answer must therefore be 44:
-11 x -4 = 44
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 11 times negative 4 will always have a positive answer.
