Everyday Algebra in Metric
Like Duolingo, but for Everyday Algebra in Metric. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
26 levels across 4 sections, about 52 minutes end to end, roughly 10 days at five minutes a day. It moves through Finding Unknowns in Everyday Life, Structuring and Simplifying Expressions, Solving Multi-Step Realities, and Visualizing Patterns and Rates. It starts from scratch.

Key ideas in Everyday Algebra in Metric
- A letter like x simply stands for an unknown quantity waiting to be discovered
- The letter takes the place of a missing value in an everyday metric measurement
- Finding a missing value from a known total is the core activity of algebra
- Everyday arithmetic with a missing number is mathematically identical to solving an equation
- Subtraction undoes addition to restore an original quantity
- Multiplication undoes division when distributing or pooling metric amounts
- Reversing the operation performed on an unknown reveals what it was originally
- Numbers carrying different units like mass (kg) and length (m) cannot be added together
- Keeping units attached to numbers exposes whether an algebraic combination makes real physical sense
- Checking an answer means replacing the unknown in the starting story with your calculated number
- If the resulting arithmetic matches the known total (20 + 2 × 45 = 110 NOK), the solution is verified
- The equals sign acts like a balanced scale indicating identical values on both pans
- Both sides must hold equal total magnitude even if expressed in different terms or units
- Any mass added or removed on one side must be identically added or removed on the other side
- Modifying only one side tips the scale and breaks the mathematical equivalence
- Isolating a variable means getting it alone on one side with no extra added, subtracted, or multiplying numbers
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Everyday Algebra in Metric the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
