Texas Instruments TI-30XS Multiview User manual

What do you need to know about the TI-30XS calculator?
The math section of the GED is divided into two sections. You can not use
a calculator for the first section, which is 5 questions. You can use a
calculator for the second section. Even in the section where the calculator
is allowed, you won’t need it for many of the questions. You can use a
calculator for the Math, Science, and Social Studies sections of the GED.
However, it is important that you are comfortable with the calculator so
that it can be used as a support in the calculator-allowed section of the
test.
Some things test takers should know about the calculator:
●Use instead of =.
●To erase screen:
●Use the arrow keys to move the cursor. This includes moving up to previous
calculations:
●Basic arithmetic operations (multiplication, division, addition, subtraction).
●The difference between the negative number key and the subtraction key.
oNegative sign:
oSubtraction:
●Convert from fraction to decimal:
Practice:
a. What fraction is
equivalent to 0.875?
b. What is -344 divided by 4?
c. What is -24 times 3?
d. Which is smaller,
or 0.875?
7
9
e. What is the difference
between the coldest
temperature you’ve ever
experienced and the
hottest temperature
you’ve experienced?

Exponents
oTaking a number to the 2nd power (squaring) can be done with the x2key. First
press the number you want to square and then press .
For example:
To find 132, you would press 13 and then
oTo raise numbers to other exponents (higher than the second power), first press
the base number, then and then the exponent.
For example:
To find 26, press 2, then , then 6.
Practice:
a. 172=
b. 74=
c. Which is bigger, 23or 32?
d. Put these in size order: 264382
e. Which is greater, 65or 56?
You will notice that some buttons have words or symbols above them in green. You can use
these functions by pressing the button.
For example, to turn off calculator: Press , and then

Roots
oSquare roots: , , the number you want to find the square root of.
oCube roots: , ,
For example:
To find the square root of 144: , , 144
To find the cube root of 216: , , , 216
Note: The GED is limited to square roots (“to the 2nd power”) and cube roots (“to the 3rd
power”).
Practice:
a. What is the square root of 961?
b. What number times itself equals 784?
c. What is the cube root of 1728?
Decide if each of the next three statements is True or False.
If False, rewrite the statement so that it is true:
d. The square root of 16 is 256.
e. The cube root of 9 is 3.
f. The cube root of 343 is larger than the square root of 49.

Useful, but not necessary:
●Creating in-out tables from functions (y = 2x + 1, for example):
, , , , , , , , ,
●To enter a fraction into the calculator, press , then the numerator, then the
down arrow , then the denominator, then the right arrow .
Don’t worry too much about this. It is better to focus on understanding fractions, rather
than how to calculate them with this particular calculator.
●Holding on and hitting clear will empty memory: ,
●Convert number to percent: ,
●Scientific notation:
Some things you do not need to know for the test:
●Logarithms
●Trigonometry (sin, cos, tan)
●Pretty much all of the other buttons.
