Practise SUMPRODUCT

What you will practise

Each position is multiplied by the corresponding position in the other array. Arrays must have identical row and column dimensions.

SUMPRODUCT(array1, array2, …)

The syntax above is a guide. Read the data and each task to choose the right arguments for your formula.

3 exercises in this lesson

  1. Exercise 1 · answer in E10

    Calculate the total order value using quantities in B2:B4 and unit prices in C2:C4.

  2. Exercise 2 · answer in E10

    Calculate total extended cost using quantities in B2:B4 and unit costs in D2:D4.

  3. Exercise 3 · answer in E10

    Calculate total profit by subtracting extended cost from extended sales value.

Before you check your answer

  • Keep the source data intact. Write your answer in the highlighted result cell. Changing a source value changes the question instead of solving it.
  • Use the requested cells. Check the first and last row of a range and read its column heading. A plausible total can still come from the wrong data.
  • Reference values that can change. A fixed number may match today's sheet. A cell reference keeps the formula connected when the source values change.

How the answer is checked

The workbook evaluates your formula against the requested result. It also checks the skill being practised and tests the formula with changed source data, so a fixed answer that happens to match is not enough.

Use progressive hints when you need help, then try the task again with fresh data. Correctly solving a step opens the next exercise.
