TI-30XS Calculator Reference Sheet
The calculator reference sheet is provided on most items on the 2014 GED? Mathematical Reasoning
Mathematical Reasoning test, as well as certain items on the Scientific Reasoning and Social Studies
tests. The calculator reference sheet is provided to test-takers in order to demonstrate the functionality
of the onscreen calculator, specifically in terms of what order to click the buttons in complex problems,
such as order of operations or calculating with fractions.
To perform basic arithmetic, enter numbers and operation symbols using the standard order
of operations.

How to convert a decimal to the simplest radical form?Convert decimal 0.45 to a proper fraction in simplest form. Solution. Step 1: We drop the decimal and write the number 45 as the numerator of a fraction. Step 2: The place value of the last digit 5 is a hundredth. So, we write 100 as the denominator of the fraction to get. $0.45 = frac{45}{100}$ Step 3:
