About Decimals

Decimal numbers are a way of expressing fractions in the base-10 number system. They're essential in mathematics and everyday calculations where precision is required beyond whole numbers.

Decimal Arithmetic
  • Addition and Subtraction: Line up the decimal points and perform the operation.
  • Multiplication: Multiply as with whole numbers, then place the decimal point by counting the total number of decimal places in both factors.
  • Division: Perform regular division and place the decimal point in the quotient as needed.
Decimal Types
  • Terminating Decimals: Decimal representations that end (e.g., 0.25, 0.5).
  • Repeating Decimals: Decimal representations with a digit or sequence of digits that repeats indefinitely (e.g., 0.333..., 0.142857142857...).
  • Irrational Decimals: Non-repeating, non-terminating decimals (e.g., ฯ€ โ‰ˆ 3.14159...).
Rounding Decimals

Rounding is used to simplify decimal numbers to a specified number of decimal places:

  • Round to Nearest: Round up if the next digit is 5 or greater, otherwise round down.
  • Round Up (Ceiling): Always round up to the next value.
  • Round Down (Floor): Always round down to the previous value.
  • Truncate: Simply cut off digits beyond the specified decimal place.

Understanding Decimal Numbers

Decimal numbers are crucial in maths and everyday tasks. They allow us to express fractions in a base-10 format. Youโ€™ll find decimals in various areas, from Financial calculations to scientific measurements. Understanding how to work with them can make calculations easier and more accurate.
