Official Reference Books & Field Manuals
Welcome to the StackCalc Publications & Reference Books Hub. Engineered in the tradition of classic Corvallis engineering field manuals, our reference books are published as durable, spiral-bound lay-flat print editions ($16.00) designed specifically for laboratory benches, maker spaces, and classroom desks.
Every single problem, formula, and keystroke sequence in both volumes has been mechanically verified against the dual-core RPNCore execution engine across hundreds of unit tests.
[!NOTE] Commercial Books & Free Open-Source Curriculum:
Our comprehensive 757-page reference manuals are premium commercial publications available in spiral-bound print ($16.00). However, the complete 43-page Master Curriculum Guide, Standards Alignment Matrix, Printable Student Station Worksheets, and 3MF 3D Print Blueprints remain 100% free and open-source in our Curriculum Center and Download Center.
Featured Reference Books
SC-32 Scientific Reference Manual & Applied STEM Handbook
The definitive operational reference and applied STEM companion for university engineering students, physics laboratories, and competitive calculation practitioners. Couples 4-stack XYZT postfix dynamics with rigorous mathematical derivations: Brent's hybrid root solver (`[SOLVE]`), adaptive Romberg quadrature (`[โซfn dx]`), cubic/quadratic closed-form polynomials (`[POLY]`), complex phasors for AC network analysis, 5-variable Time Value of Money (`[TVM]`), and live 64-point LCD vector plotting (`[PLOT]`).
// COMPLETE TABLE OF CONTENTS (14 CHAPTERS + 5 APPENDICES)
SC-6 Elementary Reference Manual & Manipulative Companion
The complete classroom companion and teacher guidebook for primary and intermediate mathematics (Grades K–6). Bridges tactile Gridfinity manipulatives (Ten-Frames, 84mm Fraction Towers, 144-tile 4-color arrays, planetary gear clocks, prime factor blocks) directly into the 4-line XYZT operational stack. Teaches rhythmic skip-counting fact ladders (`[REP]`), integer division with remainders (`[รทR]`), step-by-step fraction reduction (`[SIMP]`), and the interactive 6-level Math Quiz engine.

Look Inside: Worked Mathematical Excerpts
To give educators, parents, and engineers an unvarnished preview of the typographic rigor and pedagogical clarity inside our bench books, here are two authentic excerpts from the print editions:
+=======================================================+ | 8.3 ADAPTIVE ROMBERG QUADRATURE ACCELERATION | +=======================================================+ | Numerical integral of f(x) = sin(x)/x from 0 to ฯ: | | 1. Key lower bound: 0 [ENTER] | | 2. Key upper bound: ฯ [ENTER] | | 3. Dispatch solver: [f] [โซfn dx] | | LCD displays Richardson extrapolation table: | | T: R(3,3) = 1.85193705_ | | Z: Error = 2.1400e-09_ | | Y: Evals = 64_ | | X: Result = 1.85193705_ | +=======================================================+
Clear, monospaced register stack traces showing every step of the Richardson extrapolation, ensuring complete algorithmic transparency for students and engineers.
+=======================================================+ | 3.2 DIVISION WITH REMAINDERS ([รทR]) | +=======================================================+ | Dividing 23 cookies among 4 children: | | 1. Type dividend: 23 [ENTER] | | 2. Type divisor: 4 [g] [รท] ([รทR]) | | LCD displays whole quotient & remainder together: | | Y (Line 2): 3.0000 <-- Remainder R (Left) | | X (Line 1): 5.0000 <-- Quotient Q (Each) | | Verification via Inverse [LAST X]: | | Press [xโy] [ร] [f] [ENTER] [+] | | Screen returns to original 23.0000! | +=======================================================+
Concrete manipulatives paired 1:1 with live stack operations so children understand the algebraic symmetry between division quotients, remainders, and inverse multiplication.
Physical Bench Book Craftsmanship & Specifications
In high-density STEM classrooms, maker spaces, and electronics labs, screens compete with open breadboards, soldering irons, and math manipulatives. Our Spiral-Bound Print Editions ($16.00) are engineered specifically for physical workbenches:
Continuous twin-loop mechanical wire coil stays wide open on any page without paperweights, hand pressure, or broken book spines.
Opaque, tear-resistant laser-grade paper accepts student pencil calculations, withstands repeated classroom handling, and resists graphite smudges.
Splash-resistant protective poly soft-touch cover wipes completely clean from accidental coffee, water, or science lab chemical drips.
School District Procurement & Institutional Purchasing
We support school mathematics departments, STEM academies, CTE coordinators, and homeschool co-ops with direct institutional purchasing.
Institutional Ordering Architecture: Email & Purchase Orders (Net-30)
For school districts and government educational agencies, all institutional orders are processed directly via Purchase Order and Email requisition (orders@stackcalc.io), rather than consumer web storefronts.

- Public Procurement Law Compliance: US public school districts and state universities operate under state procurement codes requiring vendor approval, formal Net-30 purchase orders, and payment via district check or direct ACH, rather than consumer credit cards.
- Vendor Packet & Paperwork: We furnish complete vendor registration packets upon request:
- Form W-9 (Signed Taxpayer Identification Number)
- EFT / ACH Direct Deposit authorization form
- Certificate of Insurance (COI)
- State vendor portal registration (Munis, Skyward, Texas BuyBoard, SAM.gov UEI)
- Sole-Source Justification: StackCalc RPN calculators and patented tactile manipulatives are proprietary educational apparatus. We provide signed Sole Source Justification Letters enabling districts to bypass mandatory multi-vendor competitive bidding.
- Zero Hidden Transaction Surcharges: Direct PO purchasing saves school districts credit card processing fees and allows educational tax-exempt certification.
