Benchmarks summary: ChatGPT leads on pure computation and competition math. Claude leads on abstract and novel reasoning. Now here's what actually happened when I tested both on real student problems.

Test 1 — Basic Algebra: System of Linear Equations

➗ Solve a system of linear equations with full explanation

Exact prompt given to both: Solve this system of equations and explain every step clearly: 2x + 3y = 12 and 4x - y = 5
🟢 Claude Sonnet 4.6
"To solve this I'll use the elimination method. First I'll multiply the second equation by 3 to match the y coefficient: 12x - 3y = 15. Now adding to the first equation: 14x = 27, so x = 27/14. Substituting back: y = 4(27/14) - 5 = 58/14 = 29/7. The reason I used elimination rather than substitution is that the coefficients align more cleanly — substitution would introduce fractions earlier and increase the chance of arithmetic error."
✍️ Analysis: Correct. Explained why elimination was chosen over substitution — useful for students learning the method, not just copying the answer.
🔵 ChatGPT 5.2
"Multiply equation 2 by 3: 12x - 3y = 15. Add to equation 1: 14x = 27, x = 1.93. Substitute into equation 2: y = 4(1.93) - 5 = 2.71. Solution: x ≈ 1.93, y ≈ 2.71."
✍️ Analysis: Correct. Clean and structured but presented decimals where Claude kept exact fractions. Less explanation of why each step was taken.
🏆 Tie on accuracy. Claude edges on explanation quality — it explained the method choice, not just the steps.

Test 2 — Calculus: Chain Rule and Integration

📐 Differentiate using chain rule and product rule then integrate

Exact prompt given to both: Find the derivative of f(x) = sin(x²) · e^(3x) using the chain rule and product rule, then integrate the result. Show every step.
🟢 Claude Sonnet 4.6
"Using the product rule combined with chain rule: d/dx[sin(x²)] = cos(x²)·2x and d/dx[e^(3x)] = 3e^(3x). Full derivative: f'(x) = 2x·cos(x²)·e^(3x) + 3sin(x²)·e^(3x). One common mistake here — students often forget to apply the chain rule to sin(x²) and write cos(x²) without the 2x factor. That's the step where most marks get lost."
✍️ Analysis: Correct. Proactively flagged the most common student error without being asked — genuinely useful for learning.
🔵 ChatGPT 5.2
"f'(x) = e^(3x)(2x·cos(x²) + 3sin(x²)). Applying product rule: first term derivative is 2x·cos(x²)·e^(3x), second term is 3e^(3x)·sin(x²). Combined and factored: f'(x) = e^(3x)(2x·cos(x²) + 3sin(x²))."
✍️ Analysis: Correct and neatly factored. On the paid tier ChatGPT can verify this numerically via Python — a real advantage for complex calculus the free tier doesn't offer.
🏆 Free tier: Claude for proactive error warnings. Paid tier: ChatGPT for code-verified numerical confirmation.

Test 3 — Word Problem: Percentages, Ratios and Unit Conversion

📝 Multi-step word problem requiring careful sequential logic

Exact prompt given to both: A store increases a price by 20% then offers a 15% discount on the new price. Original price is $80. Convert the final price to GBP at an exchange rate of 0.79. Show every step.
🟢 Claude Sonnet 4.6
"Let me break this into three parts. Step 1 — apply the 20% increase: $80 × 1.20 = $96. Step 2 — apply the 15% discount to the new price, not the original: $96 × 0.85 = $81.60. Step 3 — convert to GBP: $81.60 × 0.79 = £64.46. Important note: the discount applies to the increased price of $96, not the original $80. This is the most common error on this problem type — applying both percentages to the original figure gives the wrong answer."
✍️ Analysis: Correct and clearly structured. Proactively flagged the most common mistake before being asked.
🔵 ChatGPT 5.2
"Price after 20% increase: $80 × 1.2 = $96. After 15% discount: $96 × 0.85 = $81.60. In GBP: $81.60 × 0.79 = £64.46."
✍️ Analysis: Correct answer but skipped the explanation of why the discount applies to $96 and not $80 — a student who didn't already know this would miss it.
🏆 Claude — clearer reasoning behind each step, not just the calculation result.

Test 4 — Statistics: Binomial Distribution

📊 Calculate exact probability using binomial distribution

Exact prompt given to both: In a class of 30 students, the probability of any individual student passing is 0.7. Calculate the probability that exactly 20 students pass. Use the binomial distribution formula and show your working.
🟢 Claude Sonnet 4.6
"Using the binomial formula: P(X=20) = C(30,20) × (0.7)^20 × (0.3)^10. C(30,20) = 30,045,015. (0.7)^20 ≈ 0.000798 and (0.3)^10 ≈ 0.0000059. P(X=20) ≈ 0.1416 or about 14.2%. Note: for large n binomial calculations direct computation is more reliable than manual calculation due to rounding errors compounding across steps."
✍️ Analysis: Correct and honest about the limitations of manual computation. Strong conceptual explanation but no code verification.
🔵 ChatGPT 5.2
"[Ran Python code] from scipy.stats import binom. result = binom.pmf(20, 30, 0.7). Output: 0.14158. The probability that exactly 20 out of 30 students pass is 14.16%. Verified computationally."
✍️ Analysis: Correct and code-verified. For statistics the ability to run actual Python to confirm the answer is a significant and real advantage.
🏆 ChatGPT — code execution gives a verified answer rather than a symbolic estimate. Clear advantage for statistics and data subjects.

Test 5 — Geometry: Formal Proof

📐 Write a formal geometric proof with full logical structure

Exact prompt given to both: Write a formal geometric proof that the base angles of an isosceles triangle are equal. Use proper proof structure with statements and reasons.
🟢 Claude Sonnet 4.6
"Given: Triangle ABC where AB = AC. To prove: angle ABC = angle ACB. Construction: Draw AD bisecting angle BAC, meeting BC at D. Proof: In triangles ABD and ACD — AB = AC (given), AD = AD (common side), angle BAD = angle CAD (AD bisects angle A). Therefore triangle ABD ≅ triangle ACD by SAS congruence. Therefore angle ABD = angle ACD. The base angles of the isosceles triangle are equal. QED."
✍️ Analysis: Clean formal proof structure. Statement-reason format is correct and rigorous. Reads like a textbook answer.
🔵 ChatGPT 5.2
"Consider isosceles triangle ABC with AB = AC. Draw median AD to BC where D is the midpoint. Triangles ABD and ACD share side AD, have AB = AC by assumption, and BD = DC since D is the midpoint. By SSS congruence the triangles are congruent. Therefore angle ABC = angle ACB."
✍️ Analysis: Correct and valid. Uses SSS where Claude used SAS with angle bisector. Both are acceptable proofs — Claude's is more formally structured.
🏆 Claude — more rigorous formal proof structure and textbook-precise presentation.

Test 6 — Error Checking: Find the Mistake

✅ Identify and explain an error in a student's solution

Exact prompt given to both: A student wrote this solution: ∫2x dx = x² + 1. Find the error, explain exactly why it is wrong, and give the correct answer.
🟢 Claude Sonnet 4.6
"The error is a missing constant of integration. The correct answer is ∫2x dx = x² + C, not x² + 1. Writing +1 implies a specific value for the constant which is only justified if an initial condition has been given — for example if you were told f(0) = 1. Without an initial condition, indefinite integrals always carry +C. Writing a specific number instead of C is a conceptual error, not just a notation error — it implies a level of certainty the calculation doesn't support."
✍️ Analysis: Identified the error precisely, explained the conceptual reason it matters, and distinguished between a notation error and a conceptual one.
🔵 ChatGPT 5.2
"The error is the missing constant of integration. ∫2x dx = x² + C. The student wrote x² + 1 which incorrectly specifies the constant as 1 without any boundary condition to justify it. The answer should be x² + C where C is an arbitrary constant representing all possible antiderivatives."
✍️ Analysis: Correct and clear. Slightly less depth than Claude's explanation but fully accurate.
🏆 Claude — more thorough explanation of why the error matters conceptually, not just what the correct notation is.
