8 times 93 is 744, but what is the answer if both 8 and 93 are negative numbers? Here we will determine if the answer to negative 8 times negative 93 is positive 744 or negative 744.
There are many different ways to explain and determine if the answer to negative 8 times negative 93 is -744 or +744 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 -744 is the correct answer using basic algebra.
We will test if -744 is correct by setting up the equation negative 8 times negative 93 equals negative 744, and then simplifying the equation to see if it is true.
(-8) (-93) = (-744)
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:
| (-8) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-8) = |
|
A numerator of 744 and denominator of 93 on the right side is the same as 744 divided by 93 which is 8. Now we end up with this untrue equation:
(-8) = (8)
-8 is NOT equal to 8, thus we have proven that negative 8 times negative 93 is not equal to -744. The answer must therefore be 744:
-8 x -93 = 744
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 8 times negative 93 will always have a positive answer.
