- You are wrong if you think Mathematics is not fun
- Mathematics studies neighborhoods, groups and free groups, rings, ideals, holes, poles and removable poles, trees, growth ...

- Among objects of mathematical study are heredity, continuity, jumps, infinity, infinitesimals, paradoxes...
- Last but not the least, Mathematics studies stability, projections and values, values are often absolute but may also be extreme, local or global.
- Trigonometry aside, Mathematics comprises fields like Game Theory, Braids Theory, Knot Theory and more
- One is morally obligated not to do anything impossible
- Some numbers are square, yet others are triangular
- The next sentence is true but you must not believe it
- The previous sentence was false

- There are things distant yet near. There are others that are near yet distant.
- There are three plane regions that share exactly the same boundary.
- A continuous linear function must have the form f(x)=ax. Discontinuous linear functions look dreadful.
- A continuous function may grow considerably virtually without changing.
- You can't add apples and oranges but you can add their shapes.
- There are many things that can be added: numbers, vectors, matrices, spaces, shapes, sets, functions, equations, strings, chains...
- Among any two integers or real numbers one is larger, another smaller. But you can't compare two complex numbers.
- The only triangle with rational sides and angles is equilateral.
- 0!=1
- One is morally obligated to do everything impossible.
- The word 'fraction' derives from the Latin fractio - to break. However, there are continuous fractions.
- For every object there is a distance at which it looks its best.
- At any given time in New York there live at least two people with the same number of hairs.
- Sometimes in order to add one has to take the difference.
- Demographic tests show that the person least likely to buy Wired magazine is an American schoolteacher.
- Complex numbers are in a sense perfect while there is little doubt that perfect numbers are complex.
- You can position 10 defenders of a square castle so that on every side there will be 5 men.
- There are many things that can be multiplied: numbers, vectors, matrices, functions, equations, sets, pegs...
- A torus may be brushed smooth but a sphere can not.
- A circle may be quite useful in drawing straight lines.
- In the sequence of all integers, there are arbitrary long runs with no primes.
