The XSL stylesheet is used in tree transformation. A stylesheet contains a set of tree construction rules. The tree construction rules have two parts: a pattern that is matched against elements in the source tree and a template that constructs a portion of the result tree.

Expanded Notation. more Writing a number to show the value of each digit. It is shown as a sum of each digit multiplied by its matching place value (ones, tens, hundreds, etc.) For example: 4, = 4 × 1, + 2 × + 6 × 10 + 5 × 1.

See: Standard Notation. Composing and Decomposing Numbers. In this lesson you will learn to write decimals in expanded notation by dividing by multiplying each digit by a unit fraction. Create your free account Teacher Student.

To write a number in expanded notation, simply write each of its digits as the product of its associated place value power of Writing in expanded notation can help large numbers feel more.

The earliest form of musical notation can be found in a cuneiform tablet that was created at Nippur, in Sumer (today's Iraq), in about timberdesignmag.com tablet represents fragmentary instructions for performing music, that the music was composed in harmonies of thirds, and that it was written using a diatonic scale.

A tablet from about BC shows a more developed form of notation.
