95 times 77 is 7315, but what is the answer if both 95 and 77 are negative numbers? Here we will determine if the answer to negative 95 times negative 77 is positive 7315 or negative 7315.
There are many different ways to explain and determine if the answer to negative 95 times negative 77 is -7315 or +7315 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 -7315 is the correct answer using basic algebra.
We will test if -7315 is correct by setting up the equation negative 95 times negative 77 equals negative 7315, and then simplifying the equation to see if it is true.
(-95) (-77) = (-7315)
Divide both sides of the equation by (-77) :
|
| = |
|
The numerator and denominator on the left side both have (-77) which even each other out and can be removed:
| (-95) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-95) = |
|
A numerator of 7315 and denominator of 77 on the right side is the same as 7315 divided by 77 which is 95. Now we end up with this untrue equation:
(-95) = (95)
-95 is NOT equal to 95, thus we have proven that negative 95 times negative 77 is not equal to -7315. The answer must therefore be 7315:
-95 x -77 = 7315
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 95 times negative 77 will always have a positive answer.
