How do you solve 1−(3.1+6.05)?
1 Answer
-8.15
Explanation:
You have a situation where there is a negative sign in front of a parenthesis. It's actually a short hand way of writing "-1" only the "1" is invisible because it's implied.
Because there is a negative 1 in front of a parenthesis, it means it's being multiplied by whatever is in the parenthesis. This is known as the [distributive law of multiplication.](http://www.mathscore.com/math/practice/Distributive%20Property/)
The first thing you would want to do is ignore the positive 1, then distribute the negative one throughout the "stuff" in the parenthesis.
Negative 1 times 3.1 is -3.1, and negative 1 times 6.05 is -6.05. Once this is complete, the parenthesis are removed, and you're left with some uncomplicated numbers to combine.
1 - (3.1 + 6.05)
(I multiplied the 3.1 and the 6.05 by the negative 1.)
So now I get:
1 -3.1 - 6.05
Combining these values I have my final answer: -8.15
