Math is a crucial subject that helps students develop critical thinking and problem-solving skills. Whether you’re a substitute teacher or a permanent teacher looking for some extra practice materials, these math problems will challenge and inspire you.

Exponential Functions: Solve the following exponential equation for x: 2^x = 16.

Quadratic Equations: Solve the following quadratic equation: x^2 + 6x + 9 = 0.

Trigonometry: Given a right triangle with sides of length 3 and 4, find the length of the third side (the hypotenuse).

Logarithms: Solve the following logarithmic equation for x: log2(x) = 3.

Matrix Operations: Find the product of the following matrices: [1 2] [3 4] [3 4] [1 2]

Perimeter and Area: Find the perimeter and area of a rectangle with a width of 5 units and a length of 7 units.

Systems of Equations: Solve the following system of linear equations: 2x + y = 4 x + 2y = 6

Geometry: In a triangle with sides of length 3, 4, and 5, find the measure of each angle.

Limits: Evaluate the following limit: lim (x -> 0) (sin x) / x.

Differentiation: Given the function f(x) = x^2, find its derivative, f'(x).

These problems are just a small sample of the many types of math problems that high school students can tackle. By working through challenging problems, students will build their confidence and improve their skills in critical thinking and problem-solving. And, of course, they will also deepen their understanding of math concepts. So grab a pencil and get started!
