In Refresher math we are using math in everyday applications.  Beginning new this semester, we are starting with decimals, fractions and whole numbers.

For example, your electric meter can easily be read if you understand some basic rules.  Each of the five dials represents one digit of the present reading.   As you can see, the dials move both clockwise and counter clockwise. By subtracting yesterday's reading from today's reading, you can get a feel for how much energy (kilowatt-hours) you use each day. Keep in mind that when the power company representative reads your meter, they do NOT set it back to zero.  Therefore the dials keep turning until the next time the meter is read.  By subtracting two consecutive readings, the amount of kilowatt hours is determined for the month.
