What “verified” means here

Interpreted
You see the expression the system will solve before computation begins.
Checked
Each shown transformation has a verification record, separate from the rule that proposed it.
Bounded
When a problem is outside the supported range or cannot be verified, the solver says so instead of filling the gap.

A proof line, not a black box

This small example shows the same structure the solver uses: expression, equivalent move, and a checked result.

  1. 01 / Read2(x+3)=102(x+3)=10

    Keep the original structure visible.

  2. 02 / Distribute2x+6=102x+6=10

    Apply the same operation across the group.

  3. 03 / Isolate2x=42x=4

    Subtract six from both sides.

  4. 04 / Verifyx=2x=2

    Verified Divide both sides by two.

Supported examples

Start with a familiar line

2(x+3)=102(x+3)=10

Distribute, then isolate the variable.

12+34\frac{1}{2}+\frac{3}{4}

Keep the result exact instead of rounding.

2x+3x−42x+3x-4

Combine only terms that are actually alike.
