If Denham could have seen how visibly books of

algebraic symbols, pages all speckled with dots and dashes and twisted bars, came before her eyes as they trod the Embankment, his secret joy in her attention might have been dispersed.

However, an

algebraic symbol (letter) that stands for an unknown in a linear relationship was yet an external representation that had not been internalized and integrated into the students' prior mental structure, and thus it was rejected in favor of the lower level of representation (number symbol) which had been a tool of their mathematical communication mastered to date (Javier, 1987; Lesh, et.

These mental abilities enable the student to deal with highest level of abstraction, i.e.,

algebraic symbol system.

The second part looks at the history of

algebraic symbols, their origins in Ancient Greece and their evolution and proliferation through the centuries, intertwining the threads of many cultures, and culminating in the work of "The Last of the Magicians"--Isaac Newton.

Thus, the reader is gently encouraged to make the effort to comprehend

algebraic symbols and their rules of operation.

Hopkins argues that Husserl provides only incomplete analyses of three major issues essential for understanding the nature of modern symbolic mathematics: 1) the source and possibility of formalization itself, 2) the unity of a number, and 3) the basis upon which

algebraic symbols function as they do.

Single, double, triple and quadruple elements are referred to, together with various

algebraic symbols and cross-headings such as Type x + (fx).

In the process, Wolfram came up with new ways of manipulating the

algebraic symbols that those diagrams represent.

But, they also studied how their own students connected number sense to a variety of algebra-based representations, such as blocks, pictures of blocks, number patterns, coordinate graphs, tables,

algebraic symbols, and real-world situations.

Tricks and extension activities vary in difficulty to challenge all students as they learn opposite functions,

algebraic symbols, multiplication tables and more.

* Making the rule that a point's coordinates and coordinate lines are specified using

algebraic symbols, such as x, y, and z (Figure 11).
