66 times 53 is 3498, but what is the answer if both 66 and 53 are negative numbers? Here we will determine if the answer to negative 66 times negative 53 is positive 3498 or negative 3498.
There are many different ways to explain and determine if the answer to negative 66 times negative 53 is -3498 or +3498 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 -3498 is the correct answer using basic algebra.
We will test if -3498 is correct by setting up the equation negative 66 times negative 53 equals negative 3498, and then simplifying the equation to see if it is true.
(-66) (-53) = (-3498)
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:
| (-66) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-66) = |
|
A numerator of 3498 and denominator of 53 on the right side is the same as 3498 divided by 53 which is 66. Now we end up with this untrue equation:
(-66) = (66)
-66 is NOT equal to 66, thus we have proven that negative 66 times negative 53 is not equal to -3498. The answer must therefore be 3498:
-66 x -53 = 3498
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 66 times negative 53 will always have a positive answer.
