To remove fix mode on a Casio fx-350ES calculator, press the "MODE" button repeatedly until you reach the "Angle" or "Decimal" settings. Once there, select the "Decimal" option, and then choose "Norm" instead of "Fix." This will switch the calculator back to standard decimal notation, allowing for a variable number of decimal places in your calculations.

To use the Pythagorean theorem on a TI-83 Plus, you can simply input the formula (c = \sqrt{a^2 + b^2}) directly into the calculator. First, square the lengths of the two legs (a) and (b) by entering (a^2) and (b^2), then add those results together. Finally, use the square root function (found under the MATH button) to calculate (c). For example, if (a = 3) and (b = 4), you would enter (\sqrt{3^2 + 4^2}) to find (c).

When taking the Algebra Common Core Regents Exam, students are generally allowed to have only specific apps on their TI-84 Plus calculators. Typically, only the default applications that come pre-installed with the calculator are permitted, such as the graphing and statistical tools. Any additional apps or programs, especially those that could provide unauthorized assistance, should be removed prior to the exam. It's always best to check the latest guidelines from the New York State Education Department for the most accurate information.

Yes, you can use a scientific calculator on the New York State Regents Chemistry Exam. However, it is important to note that certain types of calculators, such as those with graphing capabilities or those that can connect to the internet, are not allowed. Students should ensure their calculators comply with the exam's guidelines to avoid any issues on test day.

The slide rule was invented in the 17th century, with its development attributed to several mathematicians.
