3 times 58 is 174, but what is the answer if both 3 and 58 are negative numbers? Here we will determine if the answer to negative 3 times negative 58 is positive 174 or negative 174.
There are many different ways to explain and determine if the answer to negative 3 times negative 58 is -174 or +174 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 -174 is the correct answer using basic algebra.
We will test if -174 is correct by setting up the equation negative 3 times negative 58 equals negative 174, and then simplifying the equation to see if it is true.
(-3) (-58) = (-174)
Divide both sides of the equation by (-58) :
|
| = |
|
The numerator and denominator on the left side both have (-58) 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 174 and denominator of 58 on the right side is the same as 174 divided by 58 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 58 is not equal to -174. The answer must therefore be 174:
-3 x -58 = 174
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 3 times negative 58 will always have a positive answer.
