88 times 93 is 8184, but what is the answer if both 88 and 93 are negative numbers? Here we will determine if the answer to negative 88 times negative 93 is positive 8184 or negative 8184.
There are many different ways to explain and determine if the answer to negative 88 times negative 93 is -8184 or +8184 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 -8184 is the correct answer using basic algebra.
We will test if -8184 is correct by setting up the equation negative 88 times negative 93 equals negative 8184, and then simplifying the equation to see if it is true.
(-88) (-93) = (-8184)
Divide both sides of the equation by (-93) :
|
| = |
|
The numerator and denominator on the left side both have (-93) which even each other out and can be removed:
| (-88) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-88) = |
|
A numerator of 8184 and denominator of 93 on the right side is the same as 8184 divided by 93 which is 88. Now we end up with this untrue equation:
(-88) = (88)
-88 is NOT equal to 88, thus we have proven that negative 88 times negative 93 is not equal to -8184. The answer must therefore be 8184:
-88 x -93 = 8184
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 88 times negative 93 will always have a positive answer.
