EXAMPLE 01A parent walkthrough
∫ x·eˣ dx (by parts)
Show them: Set u = x, dv = eˣdx; then du = dx, v = eˣ
Say: Formula: uv - ∫v du = x·eˣ - ∫eˣ dx
Say: = x·eˣ - eˣ + C
FINAL ANSWER
x·eˣ - eˣ + C

What is Kumon Math Level X?
Kumon Math Level X (Advanced Calculus) is the 21st of 21 levels in the Kumon math program, where children learn advanced integration techniques and an introduction to differential equations. It typically aligns with university+ schoolwork, though Kumon places children by ability rather than age, so the grade is a guide, not a rule.
Level X builds directly on Math Level O: Integration and prepares children for study beyond the program. It is one of 21 Kumon math levels covered in this independent parent guide series.
This is an independent parent guide, not an official curriculum or placement assessment. Topics and pace can vary; your child’s instructor can confirm their current work.
- Integrate by parts
- Use partial fractions
- Solve basic differential equations
- Test series for convergence
- Apply advanced calculus techniques
How do I help my child with Level X?
Work through one example together, then let your child try the next one alone. A few small problems to try together — let your child attempt each first, then use these prompts when they need a nudge.

EXAMPLE 02A parent walkthrough
Solve dy/dx = 2x
Show them: Separate: dy = 2x dx
Say: Integrate both sides
Say: y = x² + C
FINAL ANSWER
y = x² + C
How can parents support Level X?
Short, calm, and daily beats long and pressured. These small habits make Level X stick — pick one and start tonight.
By parts: choose u by LIATE order (Log, Inverse trig, Algebraic, Trig, Exponential)
Differential equations just ask: what function has this derivative?
X is rare air — most students never reach it; celebrate it
