2 times 88 is 176, but what is the answer if both 2 and 88 are negative numbers? Here we will determine if the answer to negative 2 times negative 88 is positive 176 or negative 176.
There are many different ways to explain and determine if the answer to negative 2 times negative 88 is -176 or +176 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 -176 is the correct answer using basic algebra.
We will test if -176 is correct by setting up the equation negative 2 times negative 88 equals negative 176, and then simplifying the equation to see if it is true.
(-2) (-88) = (-176)
Divide both sides of the equation by (-88) :
| = |
|
The numerator and denominator on the left side both have (-88) which even each other out and can be removed:
(-2) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
(-2) = |
|
A numerator of 176 and denominator of 88 on the right side is the same as 176 divided by 88 which is 2. Now we end up with this untrue equation:
(-2) = (2)
-2 is NOT equal to 2, thus we have proven that negative 2 times negative 88 is not equal to -176. The answer must therefore be 176:
-2 x -88 = 176
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 2 times negative 88 will always have a positive answer.
