Using the Units values in C2:C6, what is the overall total?
Formula: =SUM(C2:C6) → 36
Practice Excel online in a live spreadsheet. Edit formulas, check your work, and continue with guided exercises from beginner to advanced.
Reading about spreadsheets helps, but the skill settles in when you type a formula, change an input, and see the result move. This page gives you a small live spreadsheet for exactly that kind of Excel practice online. Start the exercise, edit any cell, and test a different formula. Nothing here requires a sign-in, and resetting the grid returns the original example whenever you want another attempt.
The exercise list below moves from cell references and totals to lookups, conditional calculations, cleanup, PivotTables, and charts. Each link opens a real FormulaCamp lesson task with its own checker. The Free or Pro badge is taken from the current course access rules, so you can see the boundary before opening a lesson. If you are new, begin with cells, a first formula, and SUM. If you already work in spreadsheets, jump to lookups, error handling, or a short dashboard project.
Use the worked answers as a review after you have tried the task yourself. They pair an exact formula with its result, so you can compare your work and then change an input to make sure the calculation still responds correctly.
