Everyday Excel
Transform blank grids and messy exports into organized, automated sheets. Learn how to write living formulas, pin references, summarize ranges, and filter tables with confidence.
Like Duolingo, but for Everyday Excel. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Making Numbers Work for You and Turning Rows into Answers. It starts from scratch.

Key ideas in Everyday Excel
- An initial equals sign (=) tells Excel to treat the contents as a dynamic formula to calculate and display the result
- Excel treats any entry starting with numbers or letters as plain text or static data
- A formula that refers to another cell treats it as a live dynamic address, not a one-time copy of its value
- Whenever an input cell changes, Excel automatically recalculates all dependent formulas across the spreadsheet
- Excel uses the asterisk (*) for multiplication rather than an 'x'
- Excel uses the forward slash (/) for division rather than an obelus (÷)
- Standard plus (+) and minus (-) symbols handle addition and subtraction in formulas
- Hardcoding raw numbers inside formulas creates hidden values that do not update when source data changes
- Referencing cells keeps worksheets audit-friendly because reviewing the formula reveals which source cells feed into the result
- Dynamic cell references keep dependent totals in sync across the workbook
- Excel evaluates division and multiplication before addition and subtraction
- Writing =A1+B1/2 divides only B1 by 2 and adds the result to A1 (producing 20 instead of 15)
- Enclosing addition in parentheses forces Excel to compute the sum before dividing
- Excel's fill handle is the small square in the bottom-right corner of an active cell
- Dragging the fill handle down a column copies the formula into every row you drag across
- Copying via the fill handle eliminates manually retyping calculations for each line item
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 Excel 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.
Here's what playing it feels like
A real question from this course. Take your best guess.
You type 50+25 into a cell and press Enter, but the screen still just shows "50+25". What happened?
