Mathematics has the potential to be both an exhilarating challenge and a potential source of frustration for students. However, the following formulas will prove indispensable regardless of where a student stands on the spectrum. We're here to ensure that every student has the support they need.

Crucial for pre-algebra and later math courses, this formula calculates the area of a rectangle.

This formula calculates the total distance around the outer edges of a rectangle by adding twice the length and twice the breadth of the rectangle.

All it takes is squaring the length of both sides to find the area of a square.

If you want the perimeter of a square, just multiply the side length by 4.

To find the area of a circle, you square the radius (multiply it by itself) and then multiply the squared radius by π. The result gives you the total area covered by the circle. This formula is essential in various fields like geometry, physics, engineering, and more.

By multiplying the radius by 2π, you determine the total length of the circle's boundary.

This method is extensively used in statistics and various mathematical word problems to determine the average value of a set of numbers. The process involves two crucial steps:

**Sum of Values**: Add up all the individual values in the dataset.**Division by Count**: Divide the sum obtained in the first step by the total count of values in the dataset.

These high school math formulas are indispensable for geometry, algebra, calculus, and more. Additionally, they provide crucial assistance during the challenging math section of the SAT®.

**The Quadratic Formula: x = −b ± √b²-4ac/2a**

This formula is an indispensable tool for solving quadratic equations, particularly in advanced algebra courses such as Algebra II and beyond. The formula provides the values of*x *that satisfy the quadratic equation ax² + bx + c =0. where a, b, and c are constants and a is not equal to zero.

**Probability: Number of favorable outcomes divided by the total number of favorable outcomes.**

Whenever you're curious about the odds of something happening, this formula is your guide.

**Distance formula: d=√(x₁ – x₂)² + (y₁ – y₂)²**

Distance (d) equals the square root of the difference between the x-coordinates of the points squared, plus the difference between their y-coordinates squared.

It might sound a bit complex, but it's basically a fancy way of finding the length of the imaginary line that connects those two points. This is super useful in both geometry and algebra, because it helps us understand the space between points and solve problems that involve distances. Just plug in the coordinates of the two points, do some math magic, and you'll know how far apart they are.

**Slope Formula: Slope = y₂ – y₁ / x₂ – x₁**

This Formula allows you to calculate the steepness of the line connecting two points on a graph, providing insight into its incline or decline.

**Slope Intercept Formula: y=mx+b**

The Slope Intercept Formula is a fundamental equation in algebra used to describe and graph a straight line, where 'm' represents the slope of the line and 'b' represents the y-intercept, the point where the line crosses the y-axis.

**Area of Triangle: Area = (1/2) (base) (height)**

This formula is indispensable in geometry for calculating the total area of a triangle.

**Sine (SOH): Sine = opposite / hypotenuse**

By dividing the length of the side opposite to an angle by the length of the hypotenuse, this formula unveils the value of that angle, proving indispensable in trigonometry and geometry problem-solving.

**Cosine (CAH): Cosine = adjacent / hypotenuse**

Just like Sine, this formula reveals hidden angles in a triangle by dividing the length of the side adjacent to the angle by the hypotenuse's length.

**Tangent (TOA): Tangent = opposite / adjacent**

This equation aids in calculating unknown angles within a triangle.

**Pythagorean Theorem: a²+b²=c²**

This theorem is used to determine the hypotenuse's length in a right triangle. For any right triangle, the hypotenuse's square equals the sum of the squares of the other two sides.

This formula is an indispensable tool for solving quadratic equations, particularly in advanced algebra courses such as Algebra II and beyond. The formula provides the values of
