Absolute values are used for determining the magnitude of a number, so they are often used for distance measurements. They are also sometimes used for financial transactions. Absolute values are used when negative values are not possible.Know More
No matter what direction it is moving, a car is also moving in a positive direction; it can never move at a negative speed. However, when a car is traveling toward a particular destination, its velocity toward it can be negative. Because of this, a car's speed is equal to the absolute value of its velocity if it is traveling directly to or away from the target.
This is because velocity is a vector value, and speed is a scalar value. Scalar units measure the overall speed of an object, which must be positive. Vector units measure speed and direction, so they can be negative.
Absolute values are also useful in some financial scenarios. The money involved in a transaction, for example, is always positive, so the absolute value can help people determine the total amount of money that moved. Stock exchanges and other financial entities are often analyzed, in part, by how much money is moved in a particular period of time, and absolute values are needed to calculate this amount.Learn more about Algebra
In mathematics, a function's domain is all the possible inputs that the function can accept without breaking and the range is all the possible outputs. A real life example of this is using a simple calculator to add two numbers together. The function is the sum of "n" plus "m," the domain is all real numbers and the output is also all real numbers.Full Answer >
The Pythagorean theorem is used often in construction, in engineering, in architecture, in design, in art and in aeronautics. The theorem states that, given a right triangle with sides a, b and c, where c represents the hypotenuse (or longest side), the sum of the square of the two sides (a squared plus b squared) is always equal to c squared.Full Answer >
A negative number added to a positive number can sum up to either a positive number, negative number or zero, depending on the size of the two numbers added together. When a positive number is added to a negative number of equal size, they will essentially cancel out each other and sum to zero.Full Answer >
