Reading a Few Basic Numbers
What are the basic numbers you should actually look at before you say you understand a company?
A handful of numbers get you most of the way: revenue, the total money coming in, and profit, what's left after costs — plus how both have changed over the past several years. You don't need to calculate anything complicated. You need to know whether the company is bringing in more than it used to, and whether it's keeping more of what it earns. Direction matters more than any single number.
You don't need ten numbers. You need three or four.
Revenue: the total money coming in the door.
Profit: what's actually left after everything gets paid.
Compare this year to a few years back. Watch the direction.
Growing steadily beats one flashy number, almost every time.

Where to actually find these numbers
Public companies publish regular reports on their own results, and financial news and data sites summarize the key figures in plain tables — you don't need to read a full report to find revenue and profit for the past several years. Ask the adult you're working with to sit with you the first time and find these numbers together for one company, so you know exactly where to look next time on your own.
Direction matters more than precision
You're not trying to calculate an exact figure by hand. You're trying to answer a simple question: over the last several years, has revenue been growing, shrinking, or flat? Has profit followed the same pattern, or gone the opposite way? That trend line tells you far more than getting one year's number exactly right, and it's the part worth double-checking before you move on to anything more detailed.
Compare a company only to itself, at first
Before comparing one company to another, compare it to its own past — this year against a few years back. That's a fair, simple comparison that doesn't require knowing anything about a different industry. Comparing across different types of companies is a later skill; comparing a company to its own history is available to you right now.
One bad year isn't the whole story
A single rough year — a dip in profit, a flat year of revenue — isn't automatically a red flag. Real businesses have uneven years for all kinds of ordinary reasons. What matters more is the pattern across several years, not any one data point in isolation. Get in the habit of looking at a run of years before drawing any conclusion at all.
Ask the adult to read one report with you
Ask to sit down together and go through one real company's numbers from start to finish, even if it takes twenty minutes and you don't understand every line. Watching someone experienced skim past the parts that don't matter and slow down on the parts that do teaches you more about what to actually look at than any list of definitions could.
Success isn't memorizing what revenue and profit mean. It's being able to open a real company's numbers, find those two figures for the last several years, and say out loud whether the trend looks like growth, decline, or something flat and steady.
