The practice sheet
Add it up
Your monthly expenses are listed below. In B7, write a formula that adds up every cost.
Every formula starts with =. Type =SUM(, then drag across B2 to B6 and press Enter.
Write in the green cells, then press Check. Click a cell while typing to insert it, drag to select a range, F4 adds $, Esc cancels.

-
One idea per challenge
Each sheet teaches a single move: adding a column, locking a reference, a first IF. Small enough to finish over coffee.

Mistakes explained

=IF(B4>50, …)when the pass mark is 50 and we'll point out that Cem scored exactly 50, so you need>=. Any formula that gets the right answer passes. Typed-in numbers don't. -
Built for memory
Typing
=VLOOKUP(yourself teaches more than reading about it ten times. The keyboard shortcuts work like the real thing.
