97 times 73 is 7081, but what is the answer if both 97 and 73 are negative numbers? Here we will determine if the answer to negative 97 times negative 73 is positive 7081 or negative 7081.
There are many different ways to explain and determine if the answer to negative 97 times negative 73 is -7081 or +7081 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 -7081 is the correct answer using basic algebra.
We will test if -7081 is correct by setting up the equation negative 97 times negative 73 equals negative 7081, and then simplifying the equation to see if it is true.
(-97) (-73) = (-7081)
Divide both sides of the equation by (-73) :
|
| = |
|
The numerator and denominator on the left side both have (-73) which even each other out and can be removed:
| (-97) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-97) = |
|
A numerator of 7081 and denominator of 73 on the right side is the same as 7081 divided by 73 which is 97. Now we end up with this untrue equation:
(-97) = (97)
-97 is NOT equal to 97, thus we have proven that negative 97 times negative 73 is not equal to -7081. The answer must therefore be 7081:
-97 x -73 = 7081
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 97 times negative 73 will always have a positive answer.
