Place value is a way of representing and comparing numbers by representing each digit as having a value relative to its position in the number. It is important in math because it We can express any number using a combination of place values such as ones, tens, hundreds, thousands, and so on. These represent how many times each number appears in the whole number. For example, in the number 5,346 the ‘5’ is in the thousands place, the ‘3’ is in the hundreds place, the ‘4’ is in the tens place, and the ‘6’ is in the one’s place.
