German term or phrase: nach Null auflösen
Berechnung des pH-Wertes, wobei die Funktion root(ausdruck,variable) die Lösung einer nach 0 aufgelösten Gleichung wiedergibt. „ausdruck“ ist die nach 0 aufgelöste Gleichung, „variable“ ist die Nennung der Variablen, für die ein Wert (eine Lösung) gesucht wird, im Beispiel cH, die Protonenkonzentration.

solve for zero
Explanation:
From the context, you have an equation from which you want an expression. Let's say you have 4x + 2 = 3y. Solving this for zero gives you the equation 4x + 2 - 3y = 0; the expression required is then 4x + 2 - 3y. See step 3 in the reference.

If I may just clarify...

The text describes the use of a function called "root" which takes two parameters: "ausdruck" and "variable". This function obviously performs the operation described by Oliver - it finds the zero (also called root) of an equation for the variable "variable". The parameter "ausdruck" is an expression derived from the equation whose root is to be found by solving that equation for zero.

nach Null auflösen
set to zero


Explanation:
From the context, it might be that the equation is set to zero.

I.e., the expression is

3y^3 + 4y^2 - 47y -18 {= 0}
but you do not enter the part in braces.

A standard form for equations.

nach Null auflösen
solve for a zero of


Explanation:
This is finding the value of the variable that make the equation (or expression) equal to zero, i.e. "finding a zero of the expression".
See Aufgabe 3 in 1st Web ref. and "solve for a zero" in the 2nd

disagree  David Willett: It doesn't fit the context. You can only find the zero(s) of an equation for a specified variable. That is not how the definition of the input expression is described here.
