Unit 8 Modes: Numeric Mode
We learned in Unit 1 that a number is made by placing the numeric indicator before letters a-j. We can say that the numeric indicator sets whatever follows into numeric mode until the effect of the number mode is broken.
Numeric mode ends when it encounters a space, a letter (other than the 10 digits), sign of punctuation (except comma, period or decimal, or a simple fraction line) or a dot 5 when used as a continuation indicator or numeric space indicator.
Again, the following symbols do NOT terminate numeric mode and are used to write larger and smaller numbers, and simple non-mathematical fractions.

The numeric indicator also turns on grade 1 mode. This means that when letters appear in the sequence of numbers following the numeric indicator they are read only as the alphabetic letter they represent.

Continuation indicator (dot 5) ⠐
This indicator is used when there is not enough room on the page for a long running number. It tells us that the number is continued on the next line. Otherwise the new line would require a numeric indicator and the long number would be read as two separate numbers.
Example:
The first 50 digits of pi are: 3.1415926535897932384626433832795(insert continuation indicator here)0288419716939937510582097494…

Numeric Space Indicator (dot 5) ⠐
When a number is written with spaces between the numbers instead of commas, we insert a numeric space indicator between the numbers. Otherwise the number would require a numeric indicator after each space and the number would be read as smaller separate numbers.
Example:
My number is 432 567 4000

NOTE: Otherwise these numbers would look like three separate numbers.
