Mathematics
Mathematics (from Greek μάθημα máthēma, "knowledge, study, learning") is the study of such topics as quantity, structure, space, and change. It has no generally accepted definition.
Training
Training is teaching, or developing in oneself or others, any skills and knowledge that relate to specific useful competencies. Training has specific goals of improving one's capability, capacity, productivity and performance. It forms the core of apprenticeships and provides the backbone of content at institutes of technology (also known as technical colleges or polytechnics). In addition to the basic training required for a trade, occupation or profession, observers of the labor-market recognize as of 2008 the need to continue training beyond initial qualifications: to maintain, upgrade and update skills throughout working life. People within many professions and occupations may refer to this sort of training as professional development
Mathematics
A mathematician, like a painter or poet, is a maker of patterns. If his patterns are more permanent than theirs, it is because they are made with ideas.

Teachers
Grave is the Master's look; his forehead wears
Thick rows of wrinkles, prints of worrying cares:
Uneasy lies the heads of all that rule,
His worst of all whose kingdom is a school.
Supreme he sits; before the awful frown
That binds his brows the boldest eye goes down;
Not more submissive Israel heard and saw
At Sinai's foot the Giver of the Law.
Oliver Wendell Holmes, Sr., The School Boy.
Mathematics
Mathematics is a versatile art; it can be applied to widely different purposes. Math has no morality; it does not care what it counts or what it proves.
