Write a whole number in words and in standard form. Write a whole number in expanded form. Mathematics involves solving problems that involve numbers. We will work with, which are any of the numbers 0, 1, 2, 3, and so on. We first need to have a thorough understanding of the number system we use. Suppose the scientists preparing a lunar command module know it has to travel 382,564 kilometers to get to the moon. How well would they do if they didnt understand this number? Would it make more of a difference if the 8 was off by 1 or if the 4 was off by 1? In this section, you will take a look at digits and place value. You will also learn how to write whole numbers in words, standard form, and expanded form based on the place values of their digits. A is one of the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. All numbers are made up of one or more digits. Numbers such as 2 have one digit, whereas numbers such as 89 have two digits. To understand what a number really means, you need to understand what the digits represent in a given number.

The position of each digit in a number tells its value, or. We can use a like the one below to easily see the place value for each digit. The place values for the digits in 1,456 are shown in this chart. In the number 1,456, the digit 1 is in the thousands place. 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. As you see above, you can tell a digits value by looking at its position. Look at the number of digits to the right of the digit, or write your number into a place-value chart, with the last digit in the ones column. Both these methods are shown in the example below. The of a number refers to a type of notation in which digits are separated into groups of three by commas. These groups of three digits are known as. For example, 893,450,243 has three periods with three digits in each period, as shown below. Lets examine the number of digits and periods in a greater number. The number of body cells in an average adult human is about one hundred trillion. This number is written as 100,000,000,000,000. Notice that there are 15 digits and 5 periods. Here is how the number would look in a place-value chart. You are now familiar with the place values of greater numbers, so lets examine a problem that involves converting from standard form to a word name. We often use word names to write numbers. A word name for 42 is forty-two. The total number of weeks in a year, 52, is written as fifty-two. For whole numbers with three digits, use the word hundred to describe how many hundreds there are in the number. For example, for the number of days in a normal year, 365, the digit 3 is in the hundreds place. The word name for the number is three hundred sixty-five.

For whole numbers with four digits, begin the name with the number of thousands, followed by the period name, as in the example below. For word names of greater numbers, begin at the left with the greatest period. For each period, write the one- to three-digit number in the period, and then the period name. See the example below. When converting word names to standard form, the word thousand tells you which period the digits are in. See the example below. Below is an example with a number containing more digits. The words million and thousand tell you which periods the digits are in. The periods are separated by commas. Some numbers in word form may not mention a specific period. For example, three million, one hundred twelve written in standard form is 3,000,112. Because the thousands period is not mentioned, you would write three zeros in the thousands period. You can use a place-value chart to make it easier to see the values of the digits. See the example below. Sometimes it is useful to write numbers in. In expanded form, the number is written as a sum of the value of each digit. You can also use a place-value chart to help write a number in expanded form. Suppose the number of cars and pick-up trucks in the U. S. at this very moment is 251,834,697. Place this number in a place-value chart. Whole numbers that are greater than 9 consist of multiple digits. Each digit in a given number has a place value. To better understand place value, numbers can be put in a place-value chart so that the value of each digit can be identified. Numbers with more than three digits can be separated into groups of three digits, known as periods. Any whole number can be expressed in standard form, expanded form, or as a word name.
