Introduction
Excel formulas are used to perform calculations and solve practical data problems. In this chapter, you will practice arithmetic calculations, formula operators, cell references, relative references, absolute references, mixed references, and copying formulas. The questions are intentionally different from each other so you can test whether you can apply Excel formulas correctly to different types of data. Excel Formulas Calculation and Cell References practice help you understand the concepts.

Question 10: Create a Product Price Calculator Using Multiple Cell References
Problem Statement
Create a product calculator that calculates the subtotal, discount amount, GST amount and final payable amount.
Use:
- Discount Rate = 10%
- GST Rate = 18%

This question combines multiplication, subtraction, percentages, absolute references and multiple formulas in one practical calculation.
Key Takeaways
- Excel formulas normally begin with the
=sign. - Arithmetic operators include
+,-,*,/and^. - Cell references allow formulas to use values stored in other cells.
- A relative reference changes when a formula is copied.
- An absolute reference, such as
$A$1, remains fixed when copied. - Mixed references can lock either the row or the column.
- Percentages can be used directly in Excel calculations.
- Formulas can be combined to solve multi-step calculations.
- Copying formulas saves time when the same calculation is required for many rows.
- Always check cell references carefully when copying complex formulas.
FAQs
1. What is an Excel formula?
An Excel formula is an expression used to perform calculations or process data. Most Excel formulas begin with the = symbol.
2. What are the basic arithmetic operators in Excel?
The main arithmetic operators are + for addition, - for subtraction, * for multiplication, / for division and ^ for powers.
3. What is a cell reference in Excel?
A cell reference identifies a cell by its column and row, such as A1, B5 or D10.
4. What is a relative cell reference?
A relative reference changes automatically when a formula is copied to another cell. For example, A1 can become A2 when copied down one row.
5. What is an absolute cell reference?
An absolute reference remains fixed when a formula is copied. For example, $A$1 always refers to cell A1.
6. What is a mixed cell reference?
A mixed reference locks either the row or column while allowing the other part to change. Examples include $A1 and A$1.
7. Why are dollar signs used in Excel formulas?
Dollar signs are used to lock cell references. For example, $B$2 keeps both the column and row fixed when the formula is copied.
8. How can I copy a formula to other cells?
Enter the formula in the first cell and drag the fill handle to the required cells. You can also copy and paste the formula.
9. How do I calculate a percentage in Excel?
For example, to calculate 10% of a value in A1, you can use:
=A1*10%
10. Why should I use cell references instead of typing numbers directly into formulas?
Cell references make formulas easier to update and reuse. If the value in the referenced cell changes, Excel can automatically recalculate the result.
