## What is CalculatorSimLab?

CalculatorSimLab is a visual, offline calculator built for everyday, scientific, engineering, measurement and learning tasks. From the home screen you can open Calculator, Measure, Unit Converter, Solve Missing Value, Visual Tools, Step-by-Step, What-If Lab, Data Lab, My Formulas, Projects, and Settings and Help.

CALCULATOR
Standard addition, subtraction, multiplication, division, percent, parentheses and full editable expressions. Undo and Redo. Scientific tools include sin, cos, tan, asin, acos, atan, log, ln, sqrt, abs, pi, e, EE, Rand, x^2, x^3, x^y, 10^x, e^x and 1/x, with DEG and RAD modes. History supports delete, rename, favorites and Save to Project. Supported results can show Exact, Decimal, Percent and Scientific formats with one-tap copy. Supported functions can show mini graphs, and quadratic graphs can show vertex and real roots. Supported calculations can open Step-by-Step solutions.

MEASURE
Feet, inch and fraction calculations with quick fractions 1/2, 1/4, 3/4, 1/8, 3/8, 5/8, 7/8, 1/16 and 1/32. Results can be viewed as decimal inches, fractional inches, feet plus inches or metric.

SOLVE MISSING VALUE
Leave one field empty and solve common formulas including Ohm's Law V=I*R, Electrical Power P=V*I, Speed v=d/t, Circle Area A=pi*r^2, Density=Mass/Volume, Force F=m*a, and Percentage=Part/Total*100.

VISUAL TOOLS
Triangle, Circle, Rectangle and Area, Volume, Slope, Angle, Percentage, Ratio, Proportion, Time Calculator, Equal Spacing, Board Feet, Concrete Volume, Flooring, Tile, Drywall, Stair Geometry and Roof/Rafter Geometry.

STEP-BY-STEP
Offline solution steps for supported arithmetic, fractions, percentages, ratio and proportion, linear equations, basic quadratics, Pythagorean calculations, basic geometry and supported conversions.

WHAT-IF LAB
Write a formula, detect variables automatically, choose one variable for a slider, set minimum and maximum values, and watch the result update live. If the formula contains x, the graph updates live too.

DATA LAB
Enter or paste numbers and calculate Count, Sum, Mean, Median, Minimum, Maximum, Range, Variance and Standard Deviation. View Histogram, Line Plot and Box Plot.

MY FORMULAS
Build reusable calculators from your own formulas. Automatic variable detection and input fields. Save, reopen, edit and delete formulas. Supports multiple variables, arithmetic, parentheses, powers, sin, cos, tan, asin, acos, atan, sqrt, log, ln, abs, floor, ceil, round, exp, min, max, pow, pi, e, scientific notation, DEG and RAD. Includes Profit and Ohm's Law examples. Save formula results to Projects.

PROJECTS
Create, rename and delete workspaces. Store notes, saved formulas and project-specific calculation history. Run calculations inside a project, save My Formulas results, rename history entries, and keep everything locally on your device.

SETTINGS AND HELP
First-launch intro, section tutorials, help buttons, Replay Welcome, Show Tutorials Again and Quick Guide Library.

Calculate it. Understand it. See it.
