Three numbers. No haul of customers.
A report: cost per piece, a price, profit per piece (and optionally net for a day). That is enough. It is not a ranking who drank more. It is not a flex. It is not an Excel olympiad. Class hears honesty. Sceptic would report if you lied about a discount.
Ondra: a list of names who bought. Nela: 8, 20, 12, net 60, next time 10 pieces. A teacher takes Nela. Ondra a ranking of thirst. Shame of a map.
A board: three numbers. A mouth: one next-time sentence. Customer names no.
Public only what teaches
It teaches: a unit, profit, leftover. It does not teach: who has pocket money. A privacy line from Cashier.
When 0 sale, a report: “we had paper, 0 takings, we learned X”. It holds. It is not shame. It is Planner of zero with no finger.
Nela wants to shorten it to “it will be fine somehow”. Ondra asks what the lesson A report for class (3 numbers) is for, when a table can do a sum. A sum does not count respect, a PIN, a trap or an envelope. The core is: Three numbers for class. 이름s and a money-box haul no.
Adults pay the rent. The card, the account and the PIN belong to a parent. A child’s email does not belong here. Pocket-money numbers do not belong on the network. If you break these rules in the lesson “A report for class (3 numbers)”, you know a word, not the course.
Nela 8-20-12. Ondra 12 names. GDPR of a class soul. The course Nela.
Practice numbers, not a bank statement. Nela has 80 Kč in the want envelope. Ondra pushes a step this lesson can name. When Nela uses the core, either it waits for a parent, or it fits the envelope. If not, anger and a hole are left — proof of pressure, not that the lesson is pointless.
A photo of a full money box onto stories. A ranking + a risk. No. Even three numbers need not onto the network. A school board is enough.
Why this right now
You are in the course Money with Martin, level Till boss. You can write numbers in a notebook or a table, but the topic is money and decisions, not Excel formulas. The account, the card and the PIN belong to a parent. A child’s email does not belong here. Do not put pocket-money numbers on the network.
This is not the Sheets with Martin course. A table may help, but the mark of success is a decision, not SUM.
You will know this lesson by one sentence: Three numbers for class. 이름s and a money-box haul no. When you can say it to a parent or a teacher, you have the core. The rest is practice, not magic.
The finale puts a sheet + a report together. With no report a team can lie to itself. With a report truth is outside honestly.
If you skip this, the next lesson in level Till boss will stand on fog. 8-20-12 and 60 for practice. 이름s are not. The network is not required — a board is enough. It is not a test for marks. It is a safety net, so “A report for class (3 numbers)” is not only a heading.
Four things you will build from the course
The course has four small projects. You do not have to do them all at once. Today you add only what this lesson can do.
🪙 Pocket money
A 14-day record: income, spending, balance. What you do not write down is as if you did not spend it — and that is a lie.
Pocket-money numbers still private.
🚌 Class trip
A budget, a reserve, a plan B. A shared till has rules.
A trip: a till report three lines, not debtors.
🎮 Game shop
V-bucks and a loot box are a purchase. A subscription keeps going.
A game: do not report who bought a pass.
🧾 Stall / mini-company
Cost, price, profit. Three numbers for the class.
A Sceptic poster and this report — two tones, both calm.
Workshop: three numbers on a strip
Write 8, 20, 12 and net for practice 60. Cross out names.
-
Three numbers + net.
-
A next-time sentence.
-
A list of names on the no.
-
Money-box stories on the no.
You count with three numbers. Twelve names is an anti-report. Delete them if they started.
Pocket money: Pocket-money numbers still private. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.
Class trip: A trip: a till report three lines, not debtors. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.
Game shop: A game: do not report who bought a pass. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.
Stall: A Sceptic poster and this report — two tones, both calm. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.
What to tell a parent with no wage and no account number: “Today I went through a report for class (3 numbers) — Three numbers for class. 이름s and a money-box haul no.” If they have no time, a slip in the notebook is enough. Stories and class chat are not enough.
I can say three numbers. If you cannot see this, let the next lesson wait. It is not shame. It is a hole in the chapter, not in you.
이름s no. If you cannot see this, let the next lesson wait. It is not shame. It is a hole in the chapter, not in you.
0 sale may go out as data. If you cannot see this, let the next lesson wait. It is not shame. It is a hole in the chapter, not in you.
Three nos here too: do not chase a ranking, do not bypass a payment lock, do not carry blame for rent. When someone hurries for a code from an SMS, those are Banker and Sceptic doors, not a workshop in a rush.
Practice: it teaches, or it maps pockets?
What onto a board?
-
8-20-12. Yes?
-
이름s who bought. No?
-
0 takings + a sentence we learned. Yes?
-
Money-box stories. No?
Now you 💪
Go through three checks. By each one, tick in your head: do I see it, or not?
- I can say three numbers.
- 이름s no.
- 0 sale may go out as data.
If something is missing, go back to the steps above. It is not a test for marks. It is a safety net, so you go on with certainty, not with a mess.
Check: 8-20-12 and 60 for practice. 이름s are not. The network is not required — a board is enough.
What to take from this lesson
- Public only teaching.
- 개인정보 of customers.
- Zero is a report.
- With no haul.
- 이름s in the examples (Nela, Ondra) are made up. Do not put your number, email or photo here.
- Next lesson: When you can do this, go to the next lesson in the same level.
