False position method of (written in modern notation) the equation . This is solved by false position, using a technique that predates formally written equations. First, guess that to obtain, on the left, . This guess is a good choice since it produces an integer value. However, 4 is not the solution of the original equation, as it gives a value which is three times too small. To compensate, multiply (currently set to 4) by 3 and substitute again to get , verifying that the solution is . Modern versions of the technique employ systematic ways of choosing new test values and are
Midfielder According to positioning along the field, attacking midfield may be divided into "left, right" and "central attacking midfield" roles but mostly important he is a striker behind the forwards. A central attacking midfielder may be referred to as a "playmaker", or "number ten" (due to the association of the number 10 shirt with this position).
