19. Always read numbers
from left to right.
Think of place value when reading
and writing number words and in
symbols.

To read a number, start with
the digits in the highest period.

numerals, we use a comma or
provide space to separate the
periods.
Example:

Using a comma: 35,911
Providing space: 35 911

same way that they are read.
