Hi Kwan,
Thanks for using Microsoft products and posting in the community.
I understand from your message that you can’t find Calculate Command function . Don’t worry, here are the steps, I hope to help you:
1.To use the Calculate command, we need to add it to the Quick Access Toolbar. To do this, click the down arrow button on the right side of the Quick Access Toolbar and select “More Commands” from the drop-down menu.
2.Select “All Commands” from the “Choose commands from” drop-down list.
3..In the list of commands on the left, scroll down to the “Calculate” command, select it, and then click “Add”.
4.The Calculate command is added to the list on the right. Click “OK” to accept the change.
5.Now you can type in and then select a simple equation (do not select the equals sign) in your Word document and click the “Formula” button. For some reason, the button is not called Calculate.
NOTE: If you use spaces in your equation. Word may turn your hyphens into dashes, which won’t work. (If you don’t use spaces in your equation, this won’t be a problem.)
I hope the information provided is useful to you, Feel free to post back if you need further assistance.
