Such numbers can be expressed as decimals. For example, the decimal 6.3 falls between the integers 6 and 7. 4 6 6.3 5 7 8 You can use a number line to decide between which whole numbers a decimal falls. Some other examples of decimals include: Decimals less than −1: Decimals between −1 and 0: Decimals between 0 and 1: Decimals greater than 1: −3.65, −12.01, −145.9 −0.65, −0.8912, −0.076 0.65, 0.8912, 0.076 3.65, 12.01, 145.9 Note that an integer can be expressed as a decimal by adding the decimal point and the digit 0. For example: 8 = 8.0 −123 = −123.0 400 = 400.0 DIGITS Every number is composed of digits. There are only ten digits in our number system: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. The term digit refers to one building block of a number; it does not refer to a number itself. For example: 356 is a number composed of three digits: 3, 5, and 6. Integers can be classified by the number of digits they contain. For example: 2, 7, and −8 are each single-digit numbers (they are each composed of one digit). 43, 63, and −14 are each double-digit numbers (composed of two digits). 500,000 and −468,024 are each six-digit numbers (composed of six digits). 789,526,622 is a nine-digit number (composed of nine digits). Non-integers are not generally classified by the number of digits they contain, since you can always add any number of zeroes at the end, on the right side of the decimal point: 9.1 = 9.10 = 9.100 * Manhattan GMAT Prep the new standard 13 Chapter 1 DIGITS & DECIMALS STRATEGY Place Value Every digit in a number has a particular place value depending on its location within the number. For example, in the number 452, the digit 2 is in the ones (or “units”) place, the digit 5 is in the tens place, and the digit 4 is in the hundreds place. The name of each location corresponds to the “value”...
