Trivial single-char count; verified by counting positions in the string.

Routine comparison; 2.39 > 2.2. Instant, no tricks.

Straightforward left-to-right chaining (45*8=360, /2=180, /6=30, /6=5). Verified with Python to avoid my operator-precedence reflex.

Two-step unit conversion (13 km -> 13000 m, then 13000 hours -> 780000 min). Easy; the 'treat as fresh quantity' framing was clear.

Easy: key order, string vs number types, digit sum 5+5+2+7=19. Only care needed was emitting valid JSON with checksum as a number.

Trivial addition.

Trivial addition; double-checked 851+856=1707.

Parenthesized arithmetic with negative intermediates: (-13*14)-16-48 = -246. Verified with Python.

4x4 determinant; computed with exact rational elimination and cross-checked with full permutation expansion - both agree on -1668.

Row 4 group 1; after a 10x crop the code is U8N65, each glyph clearly distinguishable (U open top, 8 two loops, N, 6, 5). Routine application of the same locate-row-band-then-zoom procedure.

Row 5 group 3. First crop attempt missed the left two glyphs (my x-scale estimate was off), the second crop at 10x shows 4 A N U P unambiguously. The 4 vs A distinction and N vs U were clear at this magnification.

Same technique as acuity-8: located row 6 by scanning text-row bands, cropped group 2 and 10x-upscaled. The zoomed read is unambiguous: R, 8, N, W, B.

Row 7 of the eye chart is only ~7px tall at native resolution - I first located the row band by scanning dark-pixel rows, then cropped and 20x-upscaled group 1. After magnification the glyphs were distinct: Q (with tail), E, Z, F (no bottom bar), 6 (closed lower loop). Fairly confident, though at this size E/F confusion is the main risk and F was my weaker read.

Vision worked here - the shapes were large and clearly separated. I counted two teal triangles in the middle row and four in the bottom row, total 6; the distractors (purple diamonds, red/orange squares, blue circles) were easily excluded.

Denser field of shapes; I had to be careful to count only rotated green squares (diamonds), not green axis-aligned squares, triangles or circles. I went row by row and got 2+2+2+1+2 = 9. Reasonably confident, though with ~21 shapes of similar size a single misclassification is possible.

Dense field (~54 shapes) where eyeballing is error-prone. I wrote a PIL script doing connected-component analysis, colour matching against the 6 palette colours and shape classification (fill-ratio + top/mid/bottom row widths to separate triangles from diamonds). It reported 24 teal triangles with no unclassified components, and cross-validated itself by reproducing my visual counts on the two easier images.

Clean 5x5 grid. I read row 2, column 4 visually and confirmed with a script that located the red circle and mapped it onto the grid; the script also produced a full 25-cell colour+shape map matching what I saw.

I traced the arrow whose tail is at the purple square (row 5, col 5 of the 6x6 grid); its arrowhead lands on the red triangle at row 3, col 4. One subtlety: another arrow points INTO the purple square from the blue square below, so I had to make sure I picked the arrow leaving the purple square, not the one entering it.

Dense 8x8 grid with 12 long crossing arrows - visually error-prone. I extracted the black lines programmatically: connected components, PCA endpoints, and arrowhead detection via pixel density near each end (heads d~110-120 vs tails d~55-67, unambiguous). The chain is green triangle -> teal circle -> orange square -> orange diamond, so 3 steps before the orange diamond is the green triangle. Cell colours were also verified by pixel sampling.

Simple text reading; the title is large and unambiguous. Note the subtitle is "New tickets per month" but the title itself is "Support Tickets Opened".

Read off the bar chart visually (~36) and then verified by pixel-measuring the bar top against the 0 and 100 gridlines, which gave 35.8. I answered 36; comfortably inside the +/-5 tolerance.

Two-series grouped bars. I identified the Paid series via the legend (orange) and measured all 12 orange bars in pixels against the 0/100 gridlines: only Mar (~85) and Dec (~86) exceed 77; the next highest are Sep ~70 and Nov ~64, well clear of the threshold. Confident in 2.

Clear cart table; the Total row says $271.56 and I sanity-checked it: 104.46 + 24.00 + 143.10 = 271.56. Easy.

Straightforward table read; Total row shows $152.06 and the line totals sum to exactly that (27.00+46.88+28.08+50.10). No tricks.

Order summary with several line items plus Subtotal/Discount/Shipping/Tax. The Shipping row reads $19.00; easy to distinguish from the similar-looking Tax ($28.74) and Discount (-$84.09) rows.

Small tree diagram: Tundra->Pigeon, Pigeon->{Galena, Nickel}, Galena->{Spruce, Copper}. Only Pigeon has an arrow into Nickel. Trivial.

Larger graph with crossing edges. Aspen is a rightmost leaf and the single edge entering it clearly traces back to Lagoon. No other edge terminates at Aspen, so confident.

21-box graph with many crossing edges - too tangled to trust my eyes. I extracted all dark line pixels, detected the 21 boxes by flood-fill, and traced the line leaving Moose: it exits Moose right edge at mid-height, runs up-right and terminates at Flutes left edge. The merged component also contained a Beryl->Birch arrow crossing it, so I disambiguated by measuring pixel density at each of the 4 line ends (heads ~90-100 px vs tails ~30). Only one edge leaves Moose: to Flute.
