25 times 83 is 2075, but what is the answer if both 25 and 83 are negative numbers? Here we will determine if the answer to negative 25 times negative 83 is positive 2075 or negative 2075.
There are many different ways to explain and determine if the answer to negative 25 times negative 83 is -2075 or +2075 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 -2075 is the correct answer using basic algebra.
We will test if -2075 is correct by setting up the equation negative 25 times negative 83 equals negative 2075, and then simplifying the equation to see if it is true.
(-25) (-83) = (-2075)
Divide both sides of the equation by (-83) :
|
| = |
|
The numerator and denominator on the left side both have (-83) which even each other out and can be removed:
| (-25) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-25) = |
|
A numerator of 2075 and denominator of 83 on the right side is the same as 2075 divided by 83 which is 25. Now we end up with this untrue equation:
(-25) = (25)
-25 is NOT equal to 25, thus we have proven that negative 25 times negative 83 is not equal to -2075. The answer must therefore be 2075:
-25 x -83 = 2075
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 25 times negative 83 will always have a positive answer.
