The Problem With Equations in Documents

If you've ever tried to include a solved equation in a technical document, you know the friction. You work it out by hand or in a calculator. You type the result into your doc. Then you either re-type all the steps manually — hoping you didn't miss one — or you leave them out entirely and hope your reviewer trusts the answer.

Neither is great. One is tedious. The other is opaque.

Draw to Solve is GridDoc's answer to both.

What Draw to Solve Does

Draw to Solve lets you write an equation directly on your GridDoc canvas — by hand, with a stylus or mouse, the way you'd write it on a whiteboard — and GridDoc will:

1. Recognize the equation from your handwriting
2. Solve it completely, from the expression you wrote to the final value
3. Show every step, laid out sequentially below the original expression, the way a professor would work through it on a board

The result isn't just an answer dropped into your document. It's a living worked solution — formatted, readable, and embedded directly in your layout.

How It Works

Draw anywhere on your canvas to activate Draw to Solve. GridDoc's recognition engine reads your handwritten expression — including fractions, exponents, square roots, integrals, Greek letters, and multi-step algebraic expressions — and converts it to a structured equation internally.

From there, the solver breaks the expression down into discrete steps, applying operations in the correct order, simplifying at each stage, and labeling each transformation so the reasoning is clear. The full step-by-step solution is rendered on your canvas as a formatted equation block, directly below where you drew.

If the equation references values from other blocks in your document — say, a variable defined in a table block on the same page — GridDoc pulls those in automatically and solves with live values.

What It Looks Like in Practice

Here's a simple example. Say you draw this on your canvas:

F = (m × a) + (½ × k × x²)

With m = 12 kg, a = 3.5 m/s², k = 800 N/m, and x = 0.25 m defined in a table block nearby, GridDoc solves it and shows:

Step 1:  F = (12 × 3.5) + (½ × 800 × 0.25²)
Step 2:  F = 42 + (400 × 0.0625)
Step 3:  F = 42 + 25
Step 4:  F = 67 N

Each step is numbered, clearly formatted, and stays in sync with your input values. Change m in the table and the entire solution recalculates — with every step updating to reflect the new path to the answer.

Why Showing the Work Matters

In engineering and technical fields, the answer isn't enough. Reviewers need to follow the logic. Inspectors need to verify the method. Junior team members need to learn from the process. Clients sometimes need to understand why a number is what it is, not just that it is.

A solved equation with visible steps serves all of these. It turns a bare result — a number sitting in a report with no explanation — into a traceable, verifiable, and educational piece of content.

Draw to Solve makes this possible without any extra work. You're not manually typesetting steps. You're not formatting intermediate lines. You write the equation, GridDoc does the rest.

Supported Expression Types

Draw to Solve handles a wide range of mathematical expressions:

• Arithmetic and algebra — basic operations, polynomials, factoring, simplification
• Fractions and ratios — including mixed numbers and compound fractions
• Exponents and roots — including nth roots and fractional exponents
• Trigonometry — sin, cos, tan, and their inverses
• Logarithms and exponentials — natural log, log base n, e^x
• Greek letters and common engineering notation — σ, ε, Δ, μ, and more, recognized from handwriting
• Unit-aware expressions — write units inline and GridDoc carries them through each step

For more advanced expressions — integrals, differential equations, matrix operations — Draw to Solve renders the recognized expression and flags it for the built-in formula engine, so you can still embed it in your document even if step-by-step solving isn't yet supported for that form.

Where It Fits in a Real Document

Draw to Solve isn't a calculator you open separately and paste results from. It's native to the GridDoc canvas, which means:

• It lives next to your content. Draw your equation right beside the text that references it. The solved steps appear inline, spatially positioned where they make the most sense for your reader.
• It connects to your data. Variables don't need to be typed into the equation — reference a value from any table block in your document and the solver uses the live value.
• It stays in your revision history. Every version of a solved equation is tracked, so you can see how a calculation evolved across drafts.
• It exports cleanly. When you export your document, the solved equation and its steps render as formatted content — not as an image or a linked cell, but as proper typeset math.

The Whiteboard Feeling, in a Document

The best technical explanations happen at whiteboards. You write the expression, you work through it step by step, you circle the answer. Everyone in the room can follow the logic because the steps are visible.

Draw to Solve brings that experience into a document. Not as a simulation, not as a screenshot of a whiteboard — but as live, connected, recalculating content that belongs to the document the same way every other block does.

For engineers writing calculation reports, analysts explaining models, or teachers building worked-example handouts, it changes what a document can do.
