When you see an expression that begins with this terrifying symbol, you will henceforth know that it is put there merely to give you instructions that you are now to perform the operation (if you can) of totalling up all the little bits that are indicated by the symbols that follow. The word “integral” simply means “the whole.”. Now any fool can see that if x is considered as made up of a lot of little bits, each of which is called dx, if you add them all up together you get the sum of all the dx's.
Thus ∫dx means the sum of all the little bits of x. (2) ∫ which is merely a long S, and may be called (if you like) “the sum of.” But you will find that these little bits (or elements) may be considered to be indefinitely small.
Ordinary mathematicians think it more polite to say “an element of,” instead of “a little bit of.” Just as you please. Thus dx means a little bit of x or du means a little bit of u. (1) d which merely means “a little bit of.”

The preliminary terror, which chokes off most fifth-form boys from even attempting to learn how to calculate, can be abolished once for all by simply stating what is the meaning – in common-sense terms – of the two principal symbols. Shame there's not one of these for every subfield of maths. He takes your intuitions about little bits and bigness and leads you to the door of the great machine. Ridiculously clear and friendly and quick. We are republishing this vintage work now complete with a specially commissioned new biography of the author. The chapters of this volume 'To Deliver You From the Preliminary Terrors', 'On Different Degrees of Smallness', 'On Relative Growings', 'Simplest Cases', 'What to do with Constants', 'Successive Differentiation', 'When Time Varies', 'Introducing a Useful Dodge', 'Geometrical Meaning of Differentiation', et cetera.

Written in clear, simple language and full of useful information and clear explanations, this text is ideal for the student and anyone with a desire to advance their mathematical knowledge. In writing this text the author has aimed to furnish in the most practical and understandable manner, the fundamentals of calculus, specially designed for those with an interest in the topic but with limited previous knowledge and an understandable reticence about beginning their calculus adventure. This antiquarian volume contains a concise exposition of elementary calculus, being a very simple introduction to differential and integral calculus.
