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 attack. The holding midfielder may also have responsibilities when their team has the ball. This player will make mostly short and simple passes to more attacking members of their team but may try some more difficult passes depending on the team's strategy. Marcelo Bielsa is considered as a pioneer for the use of a holding midfielder in defence. This position may be seen in the 4–2–3–1 and 4–4–2 diamond formations.
