Calculators
A calculator is a hand-held inexpensive electronic device used to perform the operations of arithmetic. The simplest calculators can only do addition, subtraction, multiplication, and division, while scientific calculators can handle exponential operations, and trigonometric and logarithmic functions.

What does the Ce mean on the calculator?
Clear Entry. So if you press the wrong number.. you can erase it without deleting your entire calculation.
How do you make your calculator say booger?
No number on a calculator can be turned upside-down to say the letter 'r.' However, for your information, here a few numbers that can be turned upside-down on a calculator: 13456780
It displays the power to which '10' would have to be raised in order to get the number you entered. That's the definition of the 'logarithm' or 'log' of a number. Examples: Enter 100. Hit 'log x'. Display '2', because 102 = 100. Enter 1000. Hit 'log x'. Display '3', because 103 = 1000. Enter 2. Hit 'log x'. Display '0.30103', because 100.30103 = 2. Enter 0.1. Hit 'log x'. Display ' -1 ', because 10-1= (1/101) = 0.1
Can you use a calculator to find an average?

What did the first calculator look like?
The first calculators were abacuses, and were often constructed as a wooden frame with beads sliding on wires. Abacuses were in use centuries before the written numerals system and are still used by some merchants, fishermen and clerks in China and elsewhere.
In 1822 Charles Babbage proposed mechanical calculators; one called a difference engine, which was capable of holding and manipulating seven numbers of 31 decimal digits each; and another more advanced mechanical programmable computer called an analytical engine. None of these designs were completely built. In 1991 the London Science Museum followed Babbage's plans to build a working difference engine using the technology and materials available in the 19th century.
The Olivetti Programma 101 was introduced in late 1965; it was a stored program machine which could read and write magnetic cards and displayed results on its built-in printer. Programming allowed conditional testing and programs could also be overlayed by reading from magnetic cards. The Olivetti Programma 101 has won many industrial design awards.
The first handheld calculator was developed by Texas Instruments in 1967. It could add, multiply, subtract, and divide, and its output device was a paper tape.
The first calculator was probably the abacus; this has several balls on wires and allows the operator (with some practice) to perform arithmatic.
Is there any games for the TI Nspire?
You can play Ti-84 games with the 84 keypad but I have yet to find games for the n-Spire CAS. So just download TI-84 games and use the 84 keypad.

An amoral calculator is a member of a society who seeks to move around rules in a specific, or calculated, manner, in order to avoid breaking the rules for his or her own personal gain. This is different than a principled objector, who seeks to deliberately violate rules he or she finds immoral.
What does memory buttons mean on a calculator?
Memory is a function that is part of nearly all basic four-function and scientific calculators. The memory is basically a variable that can be used to store a single number separately from the one on the screen, for later recall.
The buttons used to manipulate the memory usually have these labels (not all calculators have them):
M+ Adds the number on the screen to the one in the memory.
M- Subtracts the number on the screen from the one in the memory. On calculators with no M- button, you can do this by negating the number and pressing M+
MR (or RCL) Enters the number in the memory onto the screen.
MRC Pressing this once is the same as MR. Pressing it twice will clear the memory.
MS (or STO, M=>) Stores the number on screen into the memory, overwriting whatever number is already in the memory.
Garphing and CAS calculators don't have a single 'memory' variable, but will allow you to store numbers into arbitrarily named variables like x using commands similar to:
Define x = 5 x := 5 5 -> xStores 5 into the variable x.
x Displays the value of x on screen.
x ² + 5 x - 14 What use would a CAS calculator be if you couldn't use x in an expression?
Is the 69th percentile good on a bmi calculator?
Yes the 69th percentile result is considered in the healthy range.
