3 times 67 is 201, but what is the answer if both 3 and 67 are negative numbers? Here we will determine if the answer to negative 3 times negative 67 is positive 201 or negative 201.
There are many different ways to explain and determine if the answer to negative 3 times negative 67 is -201 or +201 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 -201 is the correct answer using basic algebra.
We will test if -201 is correct by setting up the equation negative 3 times negative 67 equals negative 201, and then simplifying the equation to see if it is true.
(-3) (-67) = (-201)
Divide both sides of the equation by (-67) :
|
| = |
|
The numerator and denominator on the left side both have (-67) which even each other out and can be removed:
| (-3) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-3) = |
|
A numerator of 201 and denominator of 67 on the right side is the same as 201 divided by 67 which is 3. Now we end up with this untrue equation:
(-3) = (3)
-3 is NOT equal to 3, thus we have proven that negative 3 times negative 67 is not equal to -201. The answer must therefore be 201:
-3 x -67 = 201
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 3 times negative 67 will always have a positive answer.
