Newton Manufacturing produces scientific calculators. The models are N350, N450, and the N900. Newton has planned its distribution of these products around eight customer zones: Brazil, China, France, Malaysia, U. S. Northeast, U. S. Southeast, U. S. Midwest, and U. S. West. Data for the current quarter (volume to be shipped in thousands of units) for each product and each customer zone are given in the file Newton. Newton would like to know the total number of units going to each customer zone and also the total units of each product shipped. There are several ways to get this information from the data set. One way is to use the SUMIF function.

The SUMIF function extends the SUM function by allowing the user to add the values of cells meeting a logical condition. The general form of the function is
