In Excel: multiply two cells with =A2*B2, multiply a range with =PRODUCT(A2:A10), and copy the formula down when each row needs its own result.

Click the result cell.
Type =, select the first value, type *, then select the second value.
Press Enter and format the result if it represents currency or units.
Drag or double-click the fill handle to copy the multiplication formula down a table.
What this does
Excel uses the asterisk (*) as the multiplication operator. For one row, multiply cell references directly; for many values in one formula, PRODUCT multiplies every number in a range. Because cell references adjust as you copy down, a single row formula can calculate quantity times price for an entire table. Keep the inputs visible and clearly labelled and the whole thing stays auditable — anyone who opens the file later, including you, can see at a glance exactly what feeds the result and change one assumption without hunting through the formula. Treat “multiply numbers in excel” as a small repeatable workflow rather than a one-off click you hope to remember next time. Use a small test block before the live file, so any surprise in the affected cells shows up while it is still harmless. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. That turns a calculation you can defend to a CFO or an auditor into a method you can reuse, explain, and defend when the workbook leaves your screen.
A worked example
Quantity is in A2 and unit price is in B2. Enter =A2*B2 in C2: 12 units at 4.50 returns 54.00. Fill the formula down and row 3 becomes =A3*B3 automatically. If A2:A5 holds 2, 3, 4 and 5, =PRODUCT(A2:A5) returns 120. Multiplication is the backbone of pricing sheets, inventory totals, unit conversions, weighted scores and any model where a count has to be scaled by a rate, price, percentage or factor. Check the referenced cells, argument order and result type in your workbook. Start with the worked example before changing an input, then compare the changed result with the calculation you expected. An error value or a result of a different type is a reason to inspect the inputs and arguments.
In Google Sheets
Google Sheets support for this task has not been verified. Check the function, arguments and workflow in the target product before transferring the example. Matching formula notation does not establish identical behaviour. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. For “multiply numbers in excel”, keep the input cells and the result visible while you check the formula in Excel. Follow the worked example and change one input at a time. The steps explain the workbook calculation; this page does not run a live calculator for that task.
Common mistakes
- Using x instead of *; Excel treats x as text or a name, not multiplication.
- Forgetting parentheses when multiplying part of a larger expression, such as
=(A2+B2)*C2. - Copying a formula with fixed references accidentally; use $ only when one multiplier should stay constant.
- Multiplying numbers stored as text, which can return errors or unexpected zeros until the data is converted.
Frequently asked questions
What symbol multiplies in Excel?
Use the asterisk: =A2*B2.
How do I multiply a whole column by one number?
Put the multiplier in one cell, use an absolute reference like =A2*$E$1, then fill down.
When should I use PRODUCT?
Use PRODUCT when one formula needs to multiply many cells or a whole range, such as =PRODUCT(A2:A10).
