What is place value?
Place value is the value of each digit in a number based on its position. For example, in the number 347, the "3" is in the hundreds place, the "4" is in the tens place, and the "7" is in the ones place.
How do place value positions work?
Starting from the decimal point and moving left, the positions are: ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions, and so on. To the right of the decimal, they are: tenths, hundredths, thousandths, etc.
What is the "Word Form" of a number?
The word form is the number written out in English words. For example, 1,234 in word form is "one thousand, two hundred thirty-four."
Why is place value important?
Place value is the foundation of our entire numbering system (the base-10 system). It allows us to distinguish between numbers like 15 and 51 and is essential for all mathematical operations.
