1:About
Tells you the version.
Here, 2.53MP,
“MP” as in “MathPrint” / If you have a TI-84 but it doesn’t have MathPrint, it can be upgraded to the newer software. Ask the instructor for more information.
1 / / Use the ^ key for exponents. It gives you a nice exponent box in which to put the 3.
2 / / After typing the 3 in the exponent box, use the right arrow to get out of the exponent and back to the “main” line of typesetting for the * 10.
Note that the ÷ echoes as /. / Since the answer came to be a decimal, use MATH ENTER ENTER to convert the decimal to fraction. On TI-30 XS, use 2ND FD.
3 / / The parentheses keys are above the numbers 8 and 9 on the keyboard. / Since the answer came to be a decimal, use MATH ENTER ENTER to convert the decimal to fraction. On TI-30 XS, use 2ND FD.
4 / /
5 / / In the exponent box, type the entire 6 – 5 expression.
6 / / TI-84 Fractions: ALPHA key,
then the Y= key (see the green F1 printed above the Y= key).
You get a skeleton fraction.
Numerator 9,
DownArrow to Denominator 5,
RightArrow to get out of the fraction. / Use the (-)
key for “opposite-of”
in front of the -3.
It’s important to use the – subtraction key or the (-) opposite-of keys rightly.
7 / / Lots of practice with fractions and the arrow keys!
8 / / Lots more practice with fractions and the arrow keys!! / A pure fractions problem will always give you a nice fraction answer unless you get into wildly large denominators.
9 / / Type the entire 2+4 in the numerator box of the first fraction, and similarly for the second fraction.
10 / / Type the entire 4-5 in the exponent box, then the right arrow to continue with the +. / Since the answer came to be a decimal, use MATH ENTER ENTER to convert the decimal to fraction. On TI-30 XS, use 2ND FD.
11 /
12 / / Parentheses keys again. If a problem is typeset with square brackets [ ] or curly braces { }, you use the round parentheses on the calculator… / … because the calculator gives square brackets [] and curly braces { } special meanings that could lead to wrong answers for us.
13 / / Fractions inside fractions are okay! Like in the numerator box, press the ALPHA Y= again to put a fraction inside a fraction.
14 / / Since the answer came to be a decimal, use MATH ENTER ENTER to convert the decimal to fraction. On TI-30 XS, use 2ND FD.
15 / / / Since the answer came to be a decimal, use MATH ENTER ENTER to convert the decimal to fraction. On TI-30 XS, use 2ND FD.
