Arithmetic Operations and Conversions

The video tutorial covers unit conversion between gigabytes, megabytes, kilobytes, and bytes. It explains rounding decimals to the nearest whole number, tenth, and hundredth. The tutorial also demonstrates strategies for adding and subtracting decimals using the 'give or take' and 'constant difference' methods. Finally, it calculates the area of a rectangle in square inches and converts it to square feet.
