Absolute Value...

So today we learned about absolute value. Absolute value is a distance on the number line from zero. The absolute value is the same for both positive and negative numbers.
For example, -5 and 5 have the same absolute value because they are both 5 unites from zero.
Absolute value is expressed with lines on either side of the number or variable.
Treat absolute value as its own section. Do no distribute a number across the absolute value lines like you would with parenthesis.
For more elaborate equations, once you get the absolute value by itself, you must show a positve and negetive equation and check both answers with the original equation.
