98 times 3 is 294, but what is the answer if both 98 and 3 are negative numbers? Here we will determine if the answer to negative 98 times negative 3 is positive 294 or negative 294.
There are many different ways to explain and determine if the answer to negative 98 times negative 3 is -294 or +294 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 -294 is the correct answer using basic algebra.
We will test if -294 is correct by setting up the equation negative 98 times negative 3 equals negative 294, and then simplifying the equation to see if it is true.
(-98) (-3) = (-294)
Divide both sides of the equation by (-3) :
|
| = |
|
The numerator and denominator on the left side both have (-3) which even each other out and can be removed:
| (-98) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-98) = |
|
A numerator of 294 and denominator of 3 on the right side is the same as 294 divided by 3 which is 98. Now we end up with this untrue equation:
(-98) = (98)
-98 is NOT equal to 98, thus we have proven that negative 98 times negative 3 is not equal to -294. The answer must therefore be 294:
-98 x -3 = 294
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 98 times negative 3 will always have a positive answer.
