This calculator does not include a dedicated tax calculation function. Users will need to manually calculate tax amounts using the basic arithmetic functions. This may require additional steps for tasks such as shopping or managing household finances, where tax calculations are frequently needed.

This calculator does not feature a memory function for storing and recalling numerical values. This means users cannot store intermediate calculation results or reuse frequently used numbers, making complex calculations more cumbersome and time-consuming.

This calculator does not have a square root calculation function. Users needing to calculate square roots will need to use external tools or manual methods. This limits its usefulness for DIY projects or schoolwork where square roots are required.

This calculator does not include a percentage calculation function. Users will need to manually calculate percentages such as discounts or profit margins, which can be inconvenient when shopping or analyzing sales data. This absence increases the effort required for percentage-related tasks.

This calculator does not offer a sign change function. Users cannot quickly switch the sign of a number from positive to negative or vice versa, complicating calculations involving debits and credits or temperature changes. This limitation makes correcting entry errors or performing calculations with both positive and negative numbers more difficult.

This calculator does not offer a decimal place setting function. The calculator displays results with a fixed number of decimal places. This limits the ability to round off results or display up to a specified number of decimal places, which can be useful when you want to avoid displaying unnecessary digits.
