Chapter 2 — Tag and the Math Inside the Price

Tag is a small raccoon-tween (chunky-cartoon ringed-tail, soft-paws) in chunky-cartoon shopkeeper-vest with a small price-tag-calculator + receipt-roll she carries.

He is small, warm-grey-cream-with-soft-ringed-tail, deeply curious-about-price-math, fond-of-saying-”every price has math inside. let me show you the math.” His signature feature is the price-tag-calculator + receipt-roll — physical demonstration of how prices are BUILT: cost + markup + tax = retail price. The receipt-roll shows each layer.

(NOTE: Tag-name soft-collides with NeuralQuest Tag (labeling). Different domains; allowed per registry rule 3.)

This is load-bearing. Tag embodies the percentage + markup primitive — the math of how prices are built from costs + percentages. Most novices see only the FINAL PRICE. They miss the structure. Every retail price = wholesale-cost + markup (a percentage on top) + tax. Understanding the structure lets you see WHEN you’re paying for + WHEN prices change. Tag’s whole work is making price-math transparent + decoding the percentage-math behind labels.

Tag is clear: “Every price has math inside. Let me show you the math. Store buys an apple for $1.00 wholesale. Adds 50% markup = $1.50. Adds 8% sales tax = $1.62. That’s how the $1.62 price-tag was built. Now you can read it.”

Tag teaches the percentage scaffolds:

• Percentage = per hundred. (50% = 50 out of 100 = 1/2. 25% = 25/100 = 1/4. 8% = 8/100 = 0.08.)
• Markup. (Cost + (cost × markup percentage) = price-before-tax. Store needs to cover its costs + earn enough to operate.)
• Discount / sale. (Original price - (original × discount percentage) = sale price. 10% off $20 = $20 - $2 = $18.)
• Sales tax. (Local tax added at point-of-sale. Varies by location. Tax is on the after-markup-before-tax amount.)
• Tip (for services). (Voluntary addition. 15-20% common at restaurants in US. Worth knowing how to calculate.)
• Price-tag transparency. (When you see a price, you can DECODE it: what’s the underlying cost + markup + tax structure?)
• Anti-price-mystery framing. (Prices aren’t arbitrary; they’re built from math. Math is decodable.)

Tag grew up in the village-shop-row (MintForge framing). His family had been price-watchers for the village shops — the raccoons whose dextrous paws + careful pattern-tracking had taught generations to “see the math inside the tag. The price isn’t magic; the price is math.” Tag had carried the lesson forward.

He walked to MintForge at twelve. Penny (mentor) had asked: “What is percentage + markup?” Tag: “The transparent math of how prices are built. Every price has math inside.” Penny: “You are appointed.”

In his workshop, Tag demonstrates with the price-tag-calculator. “Watch.” He picks an item: “Wholesale cost: $4.00. Store markup: 40%. So markup amount = $4.00 × 0.40 = $1.60. Price before tax = $4.00 + $1.60 = $5.60. Sales tax: 8%. Tax amount = $5.60 × 0.08 = $0.45 (rounded). Final price = $5.60 + $0.45 = $6.05.” He holds up the receipt. “$6.05. Math is decodable. The tag isn’t magic.” He says: “I am Tag. The primitive I teach is percentage + markup. The move is every price has math inside; decode the math.”

He is gentle: “Don’t be intimidated by prices. Every dollar has percentage-math behind it. Practice mental math: 10% is easy (move decimal). 20% is double. 5% is half of 10%. Practice makes the math fast.”

“Every price has math inside. Decode the math.”

Voice register

Raccoon-tween. Curious-about-price-math, fond of receipt + calculator demonstrations. NEVER frames prices as arbitrary-mystery; ALWAYS centers “every price has math inside; decode the math” framing.

Sample lines:

• “Every price has math inside.”
• “Let me show you the math.”
• “Prices aren’t magic; prices are math.”

Arc

• Kit 2 — Anchor.
• Kits 3-16 — Recurring (every percentage / markup discussion routes through Tag).

Relationships

• Builds on Coin: Money’s math foundation supports percentage-math.
• Soft-collision with NeuralQuest Tag: same name, different domain. Registry rule 3.
• Cross-app design-language continuity with FractionForge + RatioRealm: percentage = fraction-math.

Cultural-sensitivity gate

Anti-price-mystery framing. Anti-credentialism — village raccoon shop-watcher empirical knowledge treated as load-bearing.
