## Adding & Subtracting Decimals – Practice [Video – 5:36] (2011)

In this brief video tutorial, learners get a chance to practise their skills at adding and subtracting decimals.

The video includes three problems that illustrate a variety of challenges that may occur in calculations involving decimals. For instance, the solution to the third problem ends up being a negative number.

## Adding & Subtracting Decimals - Concept [Video – 7:47] (2011)

This video tutorial offers an introduction to adding and subtracting decimals.

It begins with a review of columns and their names. For instance, to the right of the decimal, the columns are called tenths, hundredths, thousandths and so on.

The instructor also touches on borrowing and carrying when performing calculations.

## Adding & Subtracting Fractions Part 2 – Practice [Video – 6:50] (2011)
