With these helpful tips and tricks in hand, you’re ready to support your student with math homework, tests, quizzes, and the SAT®! In addition to unparalleled math tutoring, iD Tech offers a wealth of math resources. Got math problems? We’ve got math solutions! In any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the legs of the right triangle. This is used to find the length of a hypotenuse in a right triangle. This equation also can be used to calculate the unknown angles of a triangle. Tangent (TOA): Tangent = opposite / adjacent Use this equation to find the unknown angles of a triangle. Cosine (CAH): Cosine = adjacent / hypotenuse This equation calculates the unknown angles of a triangle. Use this in geometry to find the total area of a triangle. Area of Triangle: Area = (1/2) (base) (height) In algebra, this will find the slope intercept of a straight line. Use this to find the angle that joins two points on a graph. This equation will calculate the distance between two points, which will be necessary in geometry and algebra. To determine the probability of an event, this equation will determine the odds of something happening. Probability: Number of favorable outcomes divided by the total number of favorable outcomes. As an added pneumonic bonus, it’s easier to remember this one to the tune of “Pop Goes the Weasel”. Students will need this to solve quadratic equations in algebra II and beyond.

The Quadratic Formula: x = −b ± √b²-4ac/2a Plus, when SAT® season arrives, they will help teens succeed on the challenging math section. These high school math formulas will come in handy in geometry, algebra, calculus and more. Useful High School and SAT® Math Formulas Useful in statistics and many more math word problems. Find the Average: Sum of total numbers divided by the number of values. This formula calculates the length of the outside of a circle. Use this to find the total area of a circle. Multiply the length of the side of the square by 4 to find the perimeter. Square the length of both sides to find the area of a square. This will calculate the total of the outer lines of a rectangle. Kids will need to know this one in pre-algebra and later math classes. Elementary & Middle School Area of Rectangle: area = length x width Math can be a fun challenge or a students’ headache: these formulas will be useful no matter where your child falls on that spectrum. Whether your child needs to brush up to tackle their homework or needs to remember the essentials for a big test or quiz, these formulas are sure to come in handy. The last thing they need is to try and recall a tricky formula on top of that! Remembering the step-by-step methodology required to solve complex math problems is demanding enough for students. So, it’s important to have all the right tools in their back pocket! As any student knows, tough math problems are difficult enough without needing to remember the right formula.
