At one time preschool did not have grades or tests. It was impossible to fail. It simply got the children out of their mother's hair. At that age, children are self motivated to learn as much as possible and as fast as possible. Grades and tests come in when children need to be compared to other children and when problems need to be corrected. If a child makes a low score in reading, that child needs additional help in reading. Some children rebel against school in the fourth grade. At that point grades and tests are necessary to show that a good student has started slacking off. Tests are necessary to show if a child is developing and at what speed. Without tests, no one would know if a child is learning anything. For years, students in some states in the northern part of the United States did not receive grades in elementary school. They enjoyed the lack of pressure. Some mastered the material faster than others. The parents had no idea how fast their children were moving through the grades. In high school, grades indicate future possibilities. Almost every student knows that low grades means a career without college. Students like to know where they stand. A high school without grades does not let a student know if he will receive a college prep diploma or a certificate of attendance.
Colleges have experimented with and without grades. Oxford and Cambridge in England did not give grades for a long time. Students needed to pass a test to get a degree. St. Johns in Annapolis, MD, avoided grades for a long time. Generally students want grades to know how they are doing.
After college, people go to seminars which do not have grades. These are training sessions. They have no tests or grades. The proof of their success or failure is whether or not a person taking them gets a promotion or makes more money. That is more than a grade. In such situations a grade would be meaningless. It is the promotions and money that counts.
In Math, a negative can be represented with -. A positive can be represented with +, or just without a -.
Positive and negative charges would have not effect on an object without charge.
It is a negative connotation.
opposites: if it is a negative, make it a positive. if it is a positive, make it a negative absolute value: take the number without any sign. if it is negative, make it positive. if it is positive, keep it as a positive,
the answer is a positive because two negative or two positive is always positive.
When the absolute value of the negative number is higher than the positive number.

Without more information your question can not be answered.
The sum of two negative numbers is positive and the sum of two negatives is negative. If you have both positive and negative numbers the sum can be either so look at the absolute value. If the negative number has a greater absolute value, the sum is negative. If the positive number has a greater absolute value the sum is positive. If the absolute values are equal, the sum is zero.
If the number is 0 or positive, then its absolute value is itself. If the integer is negative, then its absolute value will be its negative (which will be positive).To illustrate the second case, Abs(-3) = -(-3) = +3.
Terrain typically has a neutral connotation, as it simply refers to the physical features of a landscape or area without inherently expressing a positive or negative value judgment. It can be positive or negative depending on individual perspectives or specific contexts.
