## 1. What is the sumproduct function and the syntax in webgiaidap.com

### 1.1. Define:

The sumproduct function is basically a webgiaidap.com function that allows to multiply numbers in specific arrays (area) and then add the results of these products to get a final result.

It can be understood simply as follows:

Sumproduct = Sum ( Product )

Product: TichSum: Total

Sumproduct is the Sum of Products

Note:

In fact, here is a function of Difficulty on both levels:

– Confusing to write functions

– Difficult to apply to calculate in webgiaidap.com

But this function is extremely effective in many cases when you know how to use it.

### 1.2. Function syntax

= Sumproduct(Array1, Array2, Array3, …)

Array is array.

– You can use up to 255 arrays in webgiaidap.com 2007 onwards, and 30 arrays for webgiaidap.com 2003

– The size of the arrays must be the same, otherwise Sumproduct will return the #VALUE . error result

– Any data contained in the arrays is not numeric data, the function will return the result 0

## 2. How to use the advanced sumproduct function/multiple conditions.

### 2.1. Example of basic usage of the Sum of Product . function

As shown in the image above, if you do not know how to use the vlookup function, you can calculate the total revenue easily:

– Calculate revenue for each sale

– Calculate the total sales at the bottom of the sales list.

But doing so would be a bit laborious.

Solution:

Use the sumproduct function to calculate the sum of the products (product here is quantity * selling price)

The function syntax in this case is as follows:

= Sumproduct(A2:A5, B2:B5) = Sum(A2*B2, A3*B3, A4*B4, A5*B5) = 135

In there:

A2:A5: Quantity B2:B5: Selling price

### 2.2. How to use the advanced sumproduct function/multiple conditions

a/ Use sumproduct function to count with 1 condition

In the sales list in the image above, we have 2 indicators: the expected sales volume and the actual sales volume.

Our task is to count how many sales transactions have actual sales less than expected.

If you do not know how to use the sumproduct function, you will have to add an extra column and then use countif to count, which is a bit laborious and will be difficult to do when the list has thousands of transactions.

As for the sumproduct function, it’s too simple as follows:

= Sumproduct ( — (Expected Sale Area > Actual Sale Range ) = Sumproduct (–(B2:B10>C2:C10)) = 4

In just a blink of an eye.

b/ Sumproduct function with multiple conditions used to count

Continuation of part a of the advanced application sumproduct function. We add 1 more condition when counting that is:

Count the number of transactions of item A that meets the condition Actual Sales

It’s actually a lot more difficult,

We use the function as follows:

In addition, there are 3 examples in part 2.
