* Online calculators: Many free online calculators are available through search engines (Google, Bing, etc.) or dedicated math websites. These are accessed through a web browser. Search for "online calculator" or "scientific calculator online" to find many options.
* Software calculators: Some software programs (like those bundled with operating systems or specialized math software) include calculator functions.
* Physical calculators: Students can use physical calculators that they purchase from stores like Amazon, Target, Walmart, Best Buy, Staples, etc. These are then used alongside online learning.
Therefore, you don't "buy" an online school calculator in the way you might buy a specific product. You either use a free online resource or purchase a physical calculator for use with your online schooling.
