Sample Problems
Algebra · Grade 8
Solve for \(x\): \[\frac{2x+3}{5} - \frac{x-1}{3} = 2\]
Answer: \(x = 8\)
Geometry · Grade 8
In a right triangle, the two legs are \(a\) and \(b\). If \(a^2 + b^2 = 100\) and \(a - b = 2\), find the value of \(ab\).
Answer: \(ab = 24\)
Functions · Grade 10
Let \(f(x) = x^2 - 4x + 3\). Find all values of \(k\) such that the equation \(f(x) = k\) has exactly one real solution.
Answer: \(k = -1\)
Trigonometry · Grade 11
Simplify: \[\frac{\sin^2\theta - \cos^2\theta}{\sin\theta + \cos\theta} + \cos\theta\]
Answer: \(\sin\theta\)
Calculus · Grade 12
Find the area enclosed by the curves \(y = x^2\) and \(y = 2x - x^2\).
Answer: \(\dfrac{1}{3}\)
Sequences · Grade 12
The sum of the first \(n\) terms of a sequence is \(S_n = 2n^2 + 3n\). Find the general term \(a_n\) for \(n \geq 2\).
Answer: \(a_n = 4n + 1\)

About

Our Story

Gripul INC is a Texas-based technology company focused on educational content systems and AI product development.

Our foundation is a math education business established in South Korea in 2002 — now one of the region's leading academic institutions, with over $10M in annual revenue. Over two decades, we've built and refined a proprietary database of 100,000+ math problems, validated by thousands of real students.

Today, we're bringing that asset to the US market — through our online tutoring platform GripulMath, and through licensing and API partnerships with EdTech companies and AI developers.
