6 times 38 is 228, but what is the answer if both 6 and 38 are negative numbers? Here we will determine if the answer to negative 6 times negative 38 is positive 228 or negative 228.
There are many different ways to explain and determine if the answer to negative 6 times negative 38 is -228 or +228 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 -228 is the correct answer using basic algebra.
We will test if -228 is correct by setting up the equation negative 6 times negative 38 equals negative 228, and then simplifying the equation to see if it is true.
(-6) (-38) = (-228)
Divide both sides of the equation by (-38) :
|
| = |
|
The numerator and denominator on the left side both have (-38) which even each other out and can be removed:
| (-6) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-6) = |
|
A numerator of 228 and denominator of 38 on the right side is the same as 228 divided by 38 which is 6. Now we end up with this untrue equation:
(-6) = (6)
-6 is NOT equal to 6, thus we have proven that negative 6 times negative 38 is not equal to -228. The answer must therefore be 228:
-6 x -38 = 228
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 6 times negative 38 will always have a positive answer.
