Absolute value extends into the concept of modulus for complex numbers.The absolute value function is an example of a continuous but non-differentiable function (specifically at zero).Absolute value can be used in applications connecting algebra to geometry.If the absolute value expression is equal to a negative number there is no solution.Then the absolve value equation can be split into a 'positive' equation and a 'negative equation.' Treat the absolute value as a variable, and isolate the absolute value first.Once the absolute value is isolated, the absolute value can you be though of under it's distance definition to increase efficiency.Absolute value represents distance, so | x − a | = c.Knowledge of the properties of equality and some experience with absolute value would help when performing this exercise. Solve the absolute value equation: This problem provides an absolute value equation and asks the student to find all solutions and write them in the space provided.There is one type of problem in this exercise: This exercise practices solving absolute value and recognizing how these are different from but related to linear equations.
