Sinopsis
Excerpt from Primary Geometry: With Simple and Practical Examples in Plane and Projection Drawing, and Suited to All Beginners
We have also, perhaps, all heard of Arithmetic, Algebra, and Geometry as branches of Mathematics. We think of Arithmetic as ciphering with figures, or working with figures to find numbers. If we know any thing at all of Algebra, perhaps we think of it as ciphering with letters instead of figures, or with a mixture of letters and figures, in order to work out some kinds of examples which cannot be done with figures alone.
We may also have an idea that Geometry is quite different from Arithmetic or Algebra, and that it is a kind of study of lines and angles, and of figures and bodies bounded or marked by lines and angles.
All these ideas are very good so far as they go. But let us get a little fuller and clearer idea of some of these subjects. First of all, we shall need to know what quantity means.
