在一个方程式中,等号左边的那个符号就是the subject of the formula.假如这个方程有N个未知数,如果已知其中N-1个未知数的值,那么最后一个未知数就可以导成the subject of the formula的形式,并且求出来.
The statement V=U+at is said to be a formula for V in terms of U,a and t.
V,U,a and t are called symbols.
The single term on the left-hand side of the equation ,V,is called the subject of the formulae.
Provided values are given for all the symbols in a formula except one,the remaining symbol can be evaluated by using a calculator.

答案

学界并无这个位置的专业名词.等式的左右两侧完全相等.如果左面叫什么,右面也可以叫什么.
如果等式左面只有一个单一字符,不妨叫它被求项.因为它不一定是数字,所以不能叫被求数.
