DRUG CLASS AND MECHANISM: Lamotrigine is an oral drug that is used primarily for treating seizures. It is chemically unrelated to other anti-seizure drugs. The precise mechanism by which lamotrigine exerts its anti-seizure action is not known. The FDA approved lamotrigine in December 1974.
Lesson Summary. This lesson discussed the different types of cell references in Excel. You learned that cell references can be relative, absolute or mixed. The type you use in a formula is important, as each behaves differently when copied or moved.
Range of Cells. While references usually refer to individual cells-such as A1, they can also refer to a group or range of cells. Ranges are identified by the cell references of the cells in the upper left and lower right corners of the range. The two cell references used for a range are separated by a colon (:) which tells Excel or Google Spreadsheets to include all the cells between these start and end points.
