62 times 60 is 3720, but what is the answer if both 62 and 60 are negative numbers? Here we will determine if the answer to negative 62 times negative 60 is positive 3720 or negative 3720.
There are many different ways to explain and determine if the answer to negative 62 times negative 60 is -3720 or +3720 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 -3720 is the correct answer using basic algebra.
We will test if -3720 is correct by setting up the equation negative 62 times negative 60 equals negative 3720, and then simplifying the equation to see if it is true.
(-62) (-60) = (-3720)
Divide both sides of the equation by (-60) :
|
| = |
|
The numerator and denominator on the left side both have (-60) which even each other out and can be removed:
| (-62) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-62) = |
|
A numerator of 3720 and denominator of 60 on the right side is the same as 3720 divided by 60 which is 62. Now we end up with this untrue equation:
(-62) = (62)
-62 is NOT equal to 62, thus we have proven that negative 62 times negative 60 is not equal to -3720. The answer must therefore be 3720:
-62 x -60 = 3720
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 62 times negative 60 will always have a positive answer.
