Check if the clear key is working.
Check if the brackets keys are working.
Check if the sum or equal key is working.
Check if the square and square root key is working.

Functionality Test Cases

Check the addition of two integer numbers.
Check the addition of two negative numbers.
Check the addition of one positive and one negative number.
Check the subtraction of two integer numbers.
Check the subtraction of two negative numbers.
Check the subtraction of one negative and one positive number.
Check the multiplication of two integer numbers.

Check the division of a number by zero.
Check the division of a number by negative number.
Check the division of zero by any number.
Check if the functionality using BODMAS/BIDMAS works as expected.

Advanced Tests on Scientific Calculator
You can add few more tests in the scientific calculator.

Check if the sin, cos, tan and cos is operational using the keys.
Check if the x-1, x!,|x|,x^y and f(x) is operational and works as expected.
Check if the log key is operational and works as expected.
Check if the natural logarithm key i operational and works as expected.
Check if the factorial key is working as expected.
Check if the real and imaginary component keys are working as expected.
Check if the complex conjugate keys are working as expected.

Conversion Function Tests

Some of the advanced scientific calculator has the converter option. It does the conversion of angle, length, weight, area, volume, duration, currency, temperature. Make sure you write the test cases for the same.

Financial Calculator Tests

The additional keys for the financial calculator will be as shown in the image. Some calculator has the mode for enabling these keys.
