So, why do we even care about the rate of change? Well, it's actually pretty important in all sorts of real-life situations. For example, if you're trying to figure out how fast a company is growing, or how quickly a new trend is taking off, you'll need to calculate the rate of change to get a sense of what's going on.
In finance, the rate of change can help you understand how investments are performing, and whether you should buy or sell. And in sports, it can show you how a team's performance is changing over time, and whether they're on a hot streak or a losing streak. The possibilities are endless!
A key concept to get your head around is the idea of difference. When you're looking at a table, you need to find the difference between each pair of values. This will give you a sense of how things are changing from one row to the next. And the good news is, it's actually pretty easy to do.
