"Mastering Number Systems: Building a Strong Math Foundation"

"Today, we’re going to learn about the number system, which is how we write and understand numbers. We’ll start with the decimal system, the one we use every day, and then we’ll see other systems like binary, which is used in computers, and others like octal and hexadecimal. By the end, you’ll see how these different ways of counting help us in technology and math."

The number system is a way we express and understand quantities. In everyday life, we use the decimal system, which is base 10. This system uses 10 digits, from 0 to 9, and each digit’s position represents a power of 10. For example, in the number 345, the 3 is in the hundreds place, the 4 in the tens, and the 5 in the ones. Besides decimal, we also have other systems, like binary (base 2) used in computers, and hexadecimal (base 16). By understanding these systems, we can read, write, and compare numbers across different contexts, which is really useful in math, science, and computing.
