58 times 61 is 3538, but what is the answer if both 58 and 61 are negative numbers? Here we will determine if the answer to negative 58 times negative 61 is positive 3538 or negative 3538.
There are many different ways to explain and determine if the answer to negative 58 times negative 61 is -3538 or +3538 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 -3538 is the correct answer using basic algebra.
We will test if -3538 is correct by setting up the equation negative 58 times negative 61 equals negative 3538, and then simplifying the equation to see if it is true.
(-58) (-61) = (-3538)
Divide both sides of the equation by (-61) :
|
| = |
|
The numerator and denominator on the left side both have (-61) which even each other out and can be removed:
| (-58) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-58) = |
|
A numerator of 3538 and denominator of 61 on the right side is the same as 3538 divided by 61 which is 58. Now we end up with this untrue equation:
(-58) = (58)
-58 is NOT equal to 58, thus we have proven that negative 58 times negative 61 is not equal to -3538. The answer must therefore be 3538:
-58 x -61 = 3538
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 58 times negative 61 will always have a positive answer.
