CAREER-FOCUSED MASTERCLASS

The math your career actually uses.

Math Wize replaces abstract textbook drills with the exact formulas tradespeople, clinicians, dispatchers, and ministers run every day on the job. Pick a vocation, watch a worker solve a real scenario, then practice the same math on functional calculators tuned to industry codes — IRC, NEC, IPC, NMFC, ISMP, and IRS clergy rules.

Pick a job. See its math.

Each card opens into the full workflow a real worker runs: a day-in-the-life story, the tools they pull from the truck or cart, an annotated diagram of the job, the governing formula (with code citation), worked examples that reveal one step at a time, and a live calculator that grades your answer against the industry-correct value.

In the field — scenarios you'll actually solve

Tony · Plumber

20 ft of 3" drain needs ¼" per foot fall. Will it clear the joist above the slab?

↳ Total drop = 20 × 0.25 = 5" — set hangers in ½" stair-steps to stay above the 9¼" joist.

Rosa · Electrician

A 30 A continuous load on a 40 A breaker — legal under NEC?

↳ Continuous loads max at 80% of breaker → 40 × 0.80 = 32 A. 30 ≤ 32, code-compliant.

Maya · Med Assistant

Amoxicillin 40 mg/kg/day ÷ q8h for a 22 lb child. Per dose?

↳ 22 lb ÷ 2.2 = 10 kg → 400 mg/day ÷ 3 doses = 133 mg q8h. Verify with RN.

Pastor Alphonso · Minister

Housing allowance $24k, FRV $22k, actual expenses $20k. Excludable from income?

↳ IRC §107 'lesser of three' → $20,000. Remaining $4k flows to W-2 wages.

Every lesson follows the same five-step rhythm: story → tools → diagram → formula → live calculator. Miss a sub-question and it auto-queues in the Mastery practice list for spaced review.
