This lesson covers mapping diagrams. Students learn that if the x-coordinate is different in each ordered pair in a given relation, then the relation is a function. Students also learn to use mapping diagrams and the vertical line test to determine if a relation is a function.

This lesson covers absolute value. Students learn that the absolute value of a number is its distance from zero on a number line. For example, the absolute value of --8 is +8, because --8 is 8 units from zero on the number line. Note that the absolute value of any positive or negative integer is positive. Students also learn that the first step to simplifying absolute value problems is to simplify inside the absolute value, if possible.

This lesson covers subtracting decimals. Students learn to subtract decimals by first lining up the decimal points, then subtracting the numbers by column. For example, to subtract 9.514 -- 1.6, first line up the decimal points, then subtract the digits the thousandths column, to get 4 - 0, or 4, then subtract the digits in the hundredths column, to get 1 -- 0, or 1, then subtract the digits in units column, by borrowing a 1 from the 9 in the units column (which leaves an 8 in the units column), to get 15 -- 6, or 9, then subtract the digits in the units column, to get 8 -- 1, or 7. So 9.514 -- 1.6 = 7.914.
