False position method concerned with the questions of whether or not an approximation to a solution can be obtained, and if it can, how fast can the approximation be found. Two basic types of false position method can be distinguished historically, "simple false position" and "double false position". "Simple false position" is aimed at solving problems involving direct proportion. Such problems can be written algebraically in the form: determine such that if and are known. The method begins by using a test input value , and finding the corresponding output value by multiplication: . The correct answer is then found by proportional adjustment,
Midfielder Midfielder A midfielder is an association football position. Midfielders are generally positioned on the field between their team's defenders and forwards. Some midfielders play a disciplined defensive role, breaking up attacks, and are otherwise known as defensive midfielders. Others blur the boundaries, being more mobile and efficient in passing: they are commonly referred to as deep-lying midfielders, play-makers, box-to-box, or holding midfielders.
