# Write a sequence formula worksheets

It is analogous to an array of variables in a conventional computer program although certain unchanging values, once entered, could be considered, by the same analogy, constants. Sum values corresponding to non-empty cells, not including zero length strings. C10 if the corresponding cells in columns A and B are not empty, cells with zero length strings are not included.

Suppose, you have an order date in column B, delivery date in column C and Qty.

How do you find the total of products that have not been delivered yet? That is, you want to know the sum of values corresponding to non-empty cells in column B and empty cells in column C. But what if you need to sum values with multiple OR criteria, i.

For example, the following formula demonstrates how to find the total of products delivered by Mike and John: Let's examine this approach now. The array argument consisting of 3 values forces your SUMIF formula to return three separate results, but since we write the formula in a single cell, it would return the first result only - i.

This approach works with numbers as well as with text values. For instance, if instead of the suppliers' names in column C, you had supplier IDs like 1, 2, 3 etc. D9 Unlike text values, numbers needn't be enclosed in double quotes in array arguments.

G4 are the cells containing your criteria, the suppliers' names in our case, as illustrated in the screenshot below. But of course, nothing prevents you from listing the values in an array criteria of your SUMIF function if you want to: D9 The result returned by both formulas will be identical to what you see in the screenshot: The formulas will be very similar to what we've just discussed.

As usual, an example might help to illustrate the point better. In our table of fruit suppliers, let's add the Delivery Date column E and find the total quantity delivered by Mike, John and Pete in October. So, assuming that the Supplies Names are in cells H1: To convert these Boolean values to 1's and 0's, you use the double minus sign, which is technically called the double unary operator.

The second unary negates the values, i.

In this lesson, Write the explicit formula for the sequence that we were working with earlier. 20, 24, 28, 32,

I hope the above explanation makes sense. Naturally, this approach works in modern versions of Excel - too, and can be deemed an old-fashioned counterpart of the SUMIFS function. In the SUMIF formulas discussed above, you have already used array arguments, but an array formula is something different.

Sum with multiple AND criteria in Excel and earlier Let's get back to the very first example where we found out a sum of amounts relating to a given fruit and supplier: The last multiplier is the sum range, C2: C9 in our case: C9 As illustrated in the screenshot below, the formula perfectly works in the latest Excel version.

If you try typing the braces manually, your formula will be converted to a text string, and it won't work. SUM array formulas in modern Excel versions Even in modern versions of Excel, orthe power of the SUM function should not be underestimated. The SUM array formula is not simply gymnastics of the mind, but has a practical value, as demonstrated in the following example. Suppose, you have two columns, B and C, and you need to count how many times column C is greater than column B, when a value in column C is greater or equal to An immediate solution that comes to mind is using the SUM array formula: B10 Don't see any practical application to the above formula?

Think about it in another way: Suppose, you have the orders list like shown in the screenshot below and you want to know how many products have not been delivered in full by a given date.

Translated into Excel's language, we have the following conditions: A value in column B Ordered items is greater than 0 Condition 2: A value in column C Delivered in less than in column B Condition 3: But hopefully, they have helped pointing you in the right direction and now you can sum values in your Excel workbooks no matter how many intricate conditions you have to consider.
