Adding decimals at a glance


Decimal numbers can be added in the same way as integers. The important thing to consider when adding decimals is place value. Tenths should be added to tenths, hundredths to hundredths, thousandths to thousandths etc. 


When using column addition to add decimals, the key is to ensure the decimal points are lined up. The values in each column can then be added in the same way that we work with whole numbers. 


A common application of decimal addition is money.


Looking forward, students can then progress to additional decimals worksheets and other number worksheets, for example a multiplying and dividing decimals worksheet or an order of operations worksheet.
