When we talk about a (b, n) pair, it means we have two numbers. The first one is called "b" and the second one is called "n." Think of "b" like a special box that can hold something inside, and "n" is a number that tells us how many things we want to put inside that box.
For example, if we have a (5, 3) pair, it means we have a box with the number 5 on it and we want to put 3 things inside that box. The things we put inside could be anything, like toys or candies.
Sometimes, we use (b, n) pairs in math. We might have an equation that looks like this: 2(b+n) = 10. This means we have to figure out what b and n are so that we can make the equation true. We know that "2" is just a number that helps us count, but we need to figure out what b and n are.
Let's say we start by guessing that b=2 and n=3. If we put those numbers into the equation, we get: 2(2+3) = 10. That's not right! But we can keep guessing until we find the right numbers. Maybe we try b=4 and n=1, and then we get: 2(4+1) = 10. That's correct! We have found the (b, n) pair that works for this equation.
So, a (b, n) pair is just two numbers that tell us about a box and how many things we want to put inside it. We can use these pairs for fun games or even for solving math problems!
