# Math in chat replies (Claude Desktop renderer)



The Claude Desktop markdown renderer has a broken inline-math path. Measured behaviour applies to **chat output**, not to files:



1. **Inline math: only `\(...\)` renders.** ``, ``, `\\(...\\)`, and `$$...$$`



written inline all print as literal source. Never use `` inline.



2. **`\(` must be preceded by a space or start-of-line.** Glued to the previous character it



silently degrades to a plain `(` and the body gets eaten by markdown emphasis



(`V_{\mathrm{cell}}` → italics). This is the most common failure: a CJK comma or a Chinese



word directly before `\(`. Write `文字 \(x\)`, not `文字\(x\)`.



The closing `\)` is safe glued to anything — `\(V=IR\)。` and `\(V=IR\)成立` both render.



3. **Hard length cap: the body must be ≤ 60 source characters.** 60 renders, 61 fails —



sharp cliff, verified at every length from 31 to 64. The count is *source* characters, not



rendered symbols: `\alpha+...` at 63 chars fails while the identical formula written with



`α` at 21 chars renders.



4. **Over 60 chars, two fixes:** compress the source with Unicode glyphs



(`? ? Δ α η μ σ π ≈ ± × ≤ ≥ ∞ ?` instead of `\partial \nabla \Delta \alpha ...`, and drop



`\mathrm` from subscripts: `V_{cell}` not `V_{\mathrm{cell}}`), or move it to a display block.



Both verified to recover previously-failing formulas.



5. **Display math: `$$...$$` on its own lines works reliably**, with no length limit and no



space rule. This is the escape hatch — when in doubt, promote to display.



6. **`aligned` loses its `&` alignment points** (rows come out centred). Use



`\begin{array}{rcl} ... &=& ... \\ \end{array}` instead; column spacing runs a bit wide but



the equals signs line up.



Practical default: keep inline math short and Unicode-dense, always leave a space before `\(`,



and push anything with a fraction-of-fractions or more than ~4 terms into `$$`.
