One-Step Division Equations - MathHelp.com - Math Help
By yourteachermathhelp
1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson students learn to solve one-step division equations. For example to solve x/4 = 2 multiply both sides of the equation by 4 to get x = 8. Next check the solution by substituting an 8 back into the original equation to get (8)/2 = 4 which is a true statement so the solution checks.

This lesson covers perimeter. Students learn that the perimeter of a figure is the distance around the figure, so the perimeter of a figure can be found by adding the lengths of its sides. Since all four sides of a square are equal in length, the perimeter of a square that has a side with a length of 8 feet is 8 + 8 + 8 + 8, or 32 feet. Since opposite sides of a rectangle are equal in length, the perimeter of a rectangle that is 4.5 meters by 6.2 meters is 4.5 + 4.5 + 6.2 + 6.2, or 21.4 meters.

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 the area of a trapezoid. Students learn that a trapezoid is a quadrilateral with one pair of parallel sides, and the formula for the area of a trapezoid is 1/2 times (base 1 + base 2) times height. For example, the area of a trapezoid that has bases of 10 centimeters and 12 centimeters and a height of 8 centimeters is 1/2 times (10 + 12) times 8, which simplifies to 1/2 times 22 times 8, or 11 times 8, which is 88 square centimeters.

Subtracting Mixed Numbers - YourTeacher.com - Pre Algebra Help
By yourteachermathhelp
For a complete lesson on subtracting mixed numbers go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson students learn to subtract mixed numbers by first subtracting the fractions then subtracting the whole numbers. For example to subtract 6 1/3 - 4 2/3 first subtract 1/3 � 2/3. However notice that 1/3 � 2/3 equals a negative fraction. In this situation the first fraction 6 1/3 can be rewritten as 5 + 1 1/3 or 5 + 4/3 or 5 4/3. Therefore the original problem 6 1/3 - 4 2/3 can be rewritten as 5 4/3 - 4 2/3. Now subtract the fractions 4/3 � 2/3 to get 2/3 and subtract the whole numbers 5 �4 to get 1. So 5 4/3 - 4 2/3 = 1 2/3. Note that some of the problems in this lesson also require the student to find a common denominator for the fractions. For example 8 5/16 - 1 1/8.
Multiplying Mixed Numbers - YourTeacher.com - Pre Algebra Help
By yourteachermathhelp
For a complete lesson on multiplying mixed numbers go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson students learn to multiply mixed numbers by first rewriting the mixed numbers as improper fractions then multiplying the improper fractions together then rewriting the resulting improper fraction as a mixed number if necessary. For example to multiply 1 8/15 x 1 1/4 first rewrite the mixed numbers as improper fractions to get 23/15 x 5/4. Next cross-cancel the 15 and 5 to 3 and 1 and we have 23/3 x 1/4. Next multiply across the numerators and denominators to get 23/12. Finally rewrite 23/12 as the mixed number 1 11/12.

This lesson covers imaginary numbers. Students learn that the imaginary number "i" is equal to the square root of -1, which means that i^2 is equal to (the square root of -1) squared, which equals -1. Students also learn to simplify imaginary numbers. For example, to simplify the square root of -81, think of it as the square root of -1 times the square root of 81, which simplifies to i times 9, or 9i. To simplify 11/8i, the first step is to get rid of the "i" in the denominator by multiplying both the numerator and the denominator of the fraction by i, to get 11i/8i^2, and remember that i^2 = -1, so we have 11i/8(-1), or 11i/-8, or -11i/8.
Adding Mixed Numbers - YourTeacher.com - Pre Algebra Help
By yourteachermathhelp
For a complete lesson on adding mixed numbers go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson students learn to add mixed numbers by first adding the fractions then adding the whole numbers. For example to add 4 2/5 + 7 4/5 first add 2/5 + 4/5 to get 6/5 then add 4 + 7 to get 11. So 4 2/5 + 7 4/5 = 11 6/5. Notice however that the answer 11 6/5 contains an improper fraction 6/5 which is the same as 1 1/5 so 11 6/5 can be rewritten as 11 + 1 1/5 which simplifies to 12 1/5. So 4 2/5 + 7 4/5 = 12 1/5. Note that some of the problems in this lesson also require the student to find a common denominator for the fractions. For example 5 1/4 + 6 3/8.

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.
