Place value is the value of where a digit is in a number. Each position in a number has a different value.
Understanding place value helps you read, write, and compare numbers correctly.
To solve these puzzles, use clues about digits in different place values and number ranges to figure out the mystery number.
Always start with the clue that gives you the most specific information.
When you have clues about specific digits in the ones or tens place, you can narrow down possibilities quickly.
Remember that the ones place is the last digit in a number.
Range clues tell you that a number is between two values, which helps limit your possibilities.
When a clue says "between" two numbers, it usually doesn't include those numbers unless specified.
Some puzzles give you several conditions that must all be true for the mystery number.
Make sure your final answer satisfies every single clue in the puzzle.
For three-digit numbers, you need to consider the hundreds place in addition to tens and ones.
With three-digit numbers, the hundreds place is the most important for determining the number's size.
