Your calculator has a lot of settings that you might never use (things like FIXED notation, or RADIAN mode), but if you're not paying attention to what you're doing, you could accidentally get your calculator in different settings than you want. For example, to get the % function, press 2nd, and then the open parenthesis key. In general, press the 2nd button any time you want to use alternate meaning of a button. How do you use the OFF feature? Press the button in the upper left corner labeled 2nd, then press the ON button. This means that the ON button is used for two purposes: to turn the calculator on and to turn it off. Notice that above the ON button, there is smaller text that says OFF. This is easy in the lower left corner there is a button labeled ON. One of the first things you'll need to do is turn your calculator on. The difference between these calculators is that the IIS is Solar Powered, and the IIB is Battery Powered.

How do you write 100 in scientific notation? In scientific notation, the letter E is used to mean “10 to the power of.” For example, 1.314E+1 means 1.314 * 101 which is 13.14. Scientific notation is another way to write a number. But when used in displaying large or small numbers, e means “times ten to the power of…”. Note that in other contexts, e = 2.71828183, the base of natural logarithms. This is simply a shortcut way to enter very large values, or tiny fractions, without using logarithms. When you enter a number in scientific notation, the TI-84 Plus CE does not automatically display answers in scientific or engineering notation. Â stands for “x10” and the calculator interprets the entire number as (123.45 x 10-2) as if it was entered with parentheses.
