Fundamentally, if you're going to be doing a lot of calculations with a slide rule, everything has to be linear, by which I mean most equations need to just be multiplications or divisions or just adding some constant number.

从根本上讲，如果您要使用计进行大量计，那么一切都必须是线性的，我的意思是大多数方程只需是乘法或除法，或者只是添加一些常数。

And the slide rule was just a kind of physical incarnation of that.
