Understanding Your Number
Understanding your number is a crucial aspect of mathematics. It involves knowing the different parts of a number and how they relate to each other. Let's break it down further:

Whole Numbers
- Whole numbers are numbers that do not have any fractions or decimals. They are made up of digits from 0 to 9.
- Examples of whole numbers include 0, 1, 2, 3, 4, etc.

Place Value
- Place value refers to the value of a digit based on its position in a number.
- For example, in the number 456, the digit 4 is in the hundreds place, the digit 5 is in the tens place, and the digit 6 is in the ones place.

Expanded Form
- Expanded form is a way of writing a number as the sum of its digits multiplied by their place values.
- For example, the expanded form of 456 would be 400 + 50 + 6.

Comparing Numbers
- When comparing numbers, you can use symbols like <,>, or = to show which number is greater, lesser, or equal.
- For example, 456 > 345 because 456 is greater than 345.

Ordering Numbers
- When ordering numbers, you arrange them from least to greatest or greatest to least.
- For example, if you have the numbers 23, 45, and 12, the order would be 12, 23, 45.
By understanding these concepts, you will be able to work with numbers more effectively and solve mathematical problems with ease. Remember to practice regularly to strengthen your number sense skills.
