TI-30XS MULTIVIEWTM CALCULATOR REFERENCE SHEET
Order of Operations
The TI-30XS MultiViewTM automatically evaluates numerical expressions using the Order of Operations based on how the expression is entered.
Example12 ÷ 2 × 3 + 5 =
1 2 ÷ 2 × 3 + 5 enter
Note that the 2 is not multiplied to the 3 before division occurs.
The correct answer is 23.
Decimals To calculate with decimals, enter the whole number, then . , then the fractional part.
Example11.526 + 5.89 - 0.4 =
1 1 . 5 2 6 + 5 . 8 9
- 0 . 4 enter
The decimal point helps line up the place value.
The correct answer is 17.016.
Fractions To calculate with fractions, use the nd button. The
answer will automatically be in its simplest form.
Example 3 __ 7 ÷ 4 __ 5 =
3 nd 7 ÷ 4 n
d 5 sto enter
This key combination works if the calculator is in Classic mode or MathPrintTM mode.
The correct answer is 15 ___ 28 .
Mixed Numbers To calculate with mixed numbers, use the 2nd nd
button. To see the fraction as an improper fraction, don’t press the 2nd x10π buttons in sequence below.
Example8 2 __ 3 × 4 3 __ 5 =
8 2nd nd 2 sto 3 sto × 4 2nd
nd 3 5 sto 2nd x10π enter
This key combination only works if the calculator is in MathPrintTM mode.
The correct answer is 39 13 ___ 15 .
Percentages To calculate with percentages, enter the percent number, then 2nd ( .
Example72% × 500 =
7 2 2nd ( × 5 0 0 enter
The correct answer is 360.

Powers & Roots To calculate with powers and roots, use the x 2 and �
buttons for powers and the 2nd x 2 and 2nd � buttons for roots.
Example212 =
2 1 x 2 enter
The correct answer is 441.
Example28 =
2 � 8 enter
The correct answer is 256.
Example √
____ 729 =
2nd x 2 7 2 9 enter
The correct answer is 27.
Example 5
√ 16807 =
5 2nd � 1 6 8 0 7 enter
The correct answer is 7.
You can use the 2nd x 2 and 2nd � buttons to also compute squares and square roots.
Scientific Notation
To calculate in scientific notation, use the x10π button as well as make sure your calculator is in Scientific notation in the mode menu.
Example6.81 × 104 + 5.201 × 104 =
6 . 8 1 x10π 4 sto +
5 . 2 0 1 x10π 4 sto enter
When you are done using scientific notation, make sure to change back to Normal in the mode menu.
The correct answer is 1.2011 × 104.
Toggle In MathPrintTM mode, you can use the toggle button to switch back and forth from exact answers (fractions, roots, π, etc.) and decimal approximations.
Example 3 __ 7 =
3 nd 7 enter
If an exact answer is not required, you can press the toggle button immediately to get a decimal approximation from an exact answer without reentering the expression.
The correct answer is 0.428571429.
