Chapter 12
Shorthand Usage Guide
Previous Chapter: Why Shorthand
Shorthand notation is useful for describing and doing calculations. The first
shorthand you meet in mathematics is decimal notation.15
15Computer
scientists may prefer base 2, 4 or 16 instead of base 10
Imagine having to write the longhand form three hundred and
twenty-five instead of the decimal notation 325 in an addition,
multiplication, division or subtraction involving this number. We use decimal
notation, like 325, to represent and write numbers briefly. Without decimal
notation, methods for doing arithmetic by hand would be awkward or much longer.
A second shorthand notation, algebraic and symbolic, is used to describe
calculations. Flexible guidelines for the selection and invention of shorthand
notation in describing calculations, are explained in this chapter.
