<p>In addition to counting cells that meet multiple conditions set by the user, the SUMPRODUCT function can also sum the contents of those cells. </p>
<p>Even though Excel has the better known <a href="http://clk.about.com/?zi=1/1hc&zu=/od/somethingiffunctions/ss/2011-04-10-Excel-2010-Sumif-Function-Step-By-Step-Tutorial.htm">SUMIF</a> and <a href="http://clk.about.com/?zi=1/1hc&zu=/od/somethingiffunctions/ss/2011-05-16-Excel-2010-Sumifs-Function-Step-By-Step-Tutorial.htm">SUMIFS</a> functions to add up values that meet one or more conditions, SUMPRODUCT still has its uses. </p>...<p><a href="http://clk.about.com/?zi=1/1hc&zu=http://spreadsheets.about.com/b/2014/04/17/sum-cells-with-sumproduct-2.htm">Read Full Post</a></p>http://spreadsheets.about.com/b/2014/04/17/sum-cells-with-sumproduct-2.htmThu, 17 Apr 2014 03:30:48 +00002014-04-17T03:30:48ZCounting with SUMPRODUCT

<p>SUMPRODUCT is one of Excel's more unique functions. </p>
<p>For one, it is <i>undocumented</i>, which means it does not get listed with other functions, nor does it provide users with the dialog box option for filling in the function's arguments.</p>...<p><a href="http://clk.about.com/?zi=1/1hc&zu=http://spreadsheets.about.com/b/2014/04/15/counting-with-sumproduct.htm">Read Full Post</a></p>http://spreadsheets.about.com/b/2014/04/15/counting-with-sumproduct.htmTue, 15 Apr 2014 08:08:33 +00002014-04-15T08:08:33ZExcel RADIANS Function
http://spreadsheets.about.com/b/2014/04/12/excel-radians-function.htm
<p>Excel has a number of functions that can help you carry out basic trigonometry operations such as finding the tangent or <a href="http://clk.about.com/?zi=1/1hc&zu=/od/excelfunctions/qt/070829_cos.htm">cosine</a> of an angle.
</p>
<p>The only problem is that these functions require that angles be measured in radians.

<p>The <a href="http://clk.about.com/?zi=1/1hc&zu=/od/excelfunctions/qt/average_functio.htm">AVERAGE Function</a> is handy to know and one that I, as a teacher, use frequently. </p>
<p>However, when it comes to student marks, rather than finding the average I often want to find a <i>weighted</i> average. </p>...<p><a href="http://clk.about.com/?zi=1/1hc&zu=http://spreadsheets.about.com/b/2014/04/03/calculate-weighted-average-in-excel-2.htm">Read Full Post</a></p>http://spreadsheets.about.com/b/2014/04/03/calculate-weighted-average-in-excel-2.htmThu, 03 Apr 2014 07:56:58 +00002014-04-03T07:56:58ZIgnore Zeros when Finding the Average

<p>While the <a href="http://clk.about.com/?zi=1/1hc&zu=/od/excelfunctions/qt/average_functio.htm">AVERAGE Function</a> is very useful when it comes to finding the arithmetic mean for a range of data, it does have limitations. </p>...<p><a href="http://clk.about.com/?zi=1/1hc&zu=http://spreadsheets.about.com/b/2014/04/01/ignore-zeros-when-finding-the-average.htm">Read Full Post</a></p>http://spreadsheets.about.com/b/2014/04/01/ignore-zeros-when-finding-the-average.htmTue, 01 Apr 2014 05:12:03 +00002014-04-01T05:12:03ZExcel INDEX Function
http://spreadsheets.about.com/b/2014/03/29/excel-index-function.htm
<p>The INDEX function uses row and column numbers from an <a href="http://clk.about.com/?zi=1/1hc&zu=/od/a/g/array_def.htm">array</a> to return the name of a specific item of <a href="http://clk.about.com/?zi=1/1hc&zu=/od/d/g/data_definition.htm">data</a> in an Excel <a href="http://clk.about.com/?zi=1/1hc&zu=/od/d/g/database.htm">database</a> or table of data.</p>
<p>INDEX is often combined with other lookup functions, such as the <a href="http://clk.about.com/?zi=1/1hc&zu=/od/lookupfunction1/ss/2011-03-01-excel-2010-match-function.htm">MATCH function</a>, to create versatile lookup formulas.</p>...<p><a href="http://clk.about.com/?zi=1/1hc&zu=http://spreadsheets.about.com/b/2014/03/29/excel-index-function.htm">Read Full Post</a></p>http://spreadsheets.about.com/b/2014/03/29/excel-index-function.htmSat, 29 Mar 2014 05:22:33 +00002014-03-29T05:22:33ZExcel Left Lookup Formula
