Preview for 6/30

Today, the topics are going to be the metric system and the English measurement system and how to switch back and forth, and how to represent numbers using scientific notation, which is useful for really big numbers and numbers really close to zero. Scientific notation is used by calculators when there are too many digits to represent a number the regular way.

If we have time, the next topic will be logarithms.

There will be a quiz at the end of class. The topics include greatest common divisor (g.c.d.), least common multiple (l.c.m), representing numbers in decimal, hexadecimal and binary, and a basic understanding of the root words and prefixes of the metric system.
