35 times 6 is 210, but what is the answer if both 35 and 6 are negative numbers? Here we will determine if the answer to negative 35 times negative 6 is positive 210 or negative 210.
There are many different ways to explain and determine if the answer to negative 35 times negative 6 is -210 or +210 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 -210 is the correct answer using basic algebra.
We will test if -210 is correct by setting up the equation negative 35 times negative 6 equals negative 210, and then simplifying the equation to see if it is true.
(-35) (-6) = (-210)
Divide both sides of the equation by (-6) :
|
| = |
|
The numerator and denominator on the left side both have (-6) 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 210 and denominator of 6 on the right side is the same as 210 divided by 6 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 6 is not equal to -210. The answer must therefore be 210:
-35 x -6 = 210
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 35 times negative 6 will always have a positive answer.
