One reason is that 2 is the first element in more than one ordered pair, 2, B and 2, Cof this set. Two other reasons, also sufficient by themselves, is that neither 3 nor 4 are first elements input of any ordered pair therein. Intuitively, a function is a process that associates to each element of a set X a unique element of a set Y.
There is some overlap among these topics, so I recommend reading the whole page. Ultimately, what are the sources of errors and of misunderstanding? What kinds of biases and erroneous preconceptions do we have?
These discoveries are remarkable in that neither involved long, involved, complicated computations. Both are fairly simple, in retrospect, to anyone who has studied them. But both involved "thinking outside the box" par excellence -- i.
Errors in Communication Some teachers are hostile to questions. That is an error made by teachers. This means listening to your students and encouraging their questions.
A teacher who only lectures, and does not encourage questions, might as well be replaced by a book or a movie.
Perhaps you identify with your brightest students, because they are most able to appreciate the beauty of the ideas you are teaching -- but the other students have greater need of your help, and they have a right to it.
A variant of teacher hostility is teacher arrogance. Actually, most of the errors listed below can be made by teachers, not just by students. However, most teachers are right far more often than their students, so students should exercise great caution when considering whether their teachers could be in error.
The remarks on communication in the next few paragraphs are for students whose teachers are receptive to questions.
For such students, a common error is that of not asking questions. To save face, just in case the error is your own, formulate it as a question rather than a statement.
For instance, instead of saying "that 5 should be a 7", you can ask "should that 5 be a 7? Now all your classmates have an error in the notes that they took in class, and they may have trouble deciphering their notes later. In the early s, I managed a computer retail store. Several of my employees were college students.
One bright your man was having difficulty with his Freshman college algebra class. I tutored him and he did very well, but invariably, he would say, "the professor worked through this problem on the board, and it was nothing like this.
I sure hope we got the correct answer. During the class, he picked a problem from the assignment to work out on the board. Very early in the problem, he made an error.

|MathML International Conference Abstract Most mathematical notation now in use is between one and five hundred years old. I will review how it developed, with precursors in antiquity and the Middle Ages, through its definition at the hands of Leibniz, Euler, Peano and others, to its widespread use in the nineteenth and twentieth centuries.|
Because of the error, he eventually reached a point from which he could no longer proceed. Rather than admitting an error and going to work to find it, he paused staring at the board for several seconds, then turned to the class and said, " The English language was not designed for mathematical clarity.
Indeed, most of the English language was not really designed at all -- it simply grew. It is not always perfectly clear.Write as a mathematical expression.
