👉 A logarithm is a mathematical function that converts one quantity into another. It's like taking the inverse of multiplication, where you're looking for the number that when multiplied together gives a given product. For example, if you have 10 apples and want to know how many oranges you can get from them, you would do: \( \frac{10}{\text{number of oranges}} = 5 \) So, 10 apples are equivalent to 5 oranges. This
