35 times 29 is 1015, but what is the answer if both 35 and 29 are negative numbers? Here we will determine if the answer to negative 35 times negative 29 is positive 1015 or negative 1015.
There are many different ways to explain and determine if the answer to negative 35 times negative 29 is -1015 or +1015 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 -1015 is the correct answer using basic algebra.
We will test if -1015 is correct by setting up the equation negative 35 times negative 29 equals negative 1015, and then simplifying the equation to see if it is true.
(-35) (-29) = (-1015)
Divide both sides of the equation by (-29) :
|
| = |
|
The numerator and denominator on the left side both have (-29) which even each other out and can be removed:
| (-35) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-35) = |
|
A numerator of 1015 and denominator of 29 on the right side is the same as 1015 divided by 29 which is 35. Now we end up with this untrue equation:
(-35) = (35)
-35 is NOT equal to 35, thus we have proven that negative 35 times negative 29 is not equal to -1015. The answer must therefore be 1015:
-35 x -29 = 1015
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 35 times negative 29 will always have a positive answer.
