Decimals are real numbers that can represent fractions or parts of a whole. They are written with a decimal point, and the numbers to the left of the point indicate how many whole numbers are included, while the numbers to the right of the point indicate the fractional part of the number. Decimals can be added, subtracted, multiplied, and divided just like whole numbers. When performing these operations, it is important to line up the decimal points so that the decimal places match, as this ensures accuracy. Decimals can also be written in expanded or scientific form. In expanded form, the number is written as the sum of the whole number and the fractional part. In scientific form, the number is written in exponential notation, which is a number with a power of 10.
