Negative 5. It's normal division, except you need to remember these rules: Positive & Negative = Negative Positive & Positive = Positive
I believe the parentheses eliminate the need for the negative sign. For example: negative $100,000 would be expressed $(100,000). Using the negative sign, it would read: -$100,000.
Well it depends on if you are talking mathematical or scientific.
In mathematics, a negative plus a negative results in a negative because you are essentially combining two debts or losses, which increases the overall debt. However, a negative times a negative equals a positive due to the properties of multiplication and the need for consistency in the arithmetic system; multiplying a negative by a negative reverses the direction of the number line, resulting in a positive value. This distinction helps maintain coherent mathematical rules and operations.
There is no need to find the square root of a negative number for sqrt(0.6)!
