#### App4Math Makes Calculations Easy

Without App4Math, your graphing calculator can be confusing. Fractions, exponents, and square roots don’t look the same as they do in your textbook. Variables are always capitalized.

Without App4Math, if you want to make

equalx-5, you have to type “-5“…and you have to be careful to use the minus key in parentheses, not the regular subtraction key. To typex, you have to use the MATH menu or thex^{3}key.^

With App4Math, everything looks right! Fractions look like real fractions. Exponents and square roots look right. Variables are lowercase.

With App4Math, if you want to make

equalx-5, just type “=x-5“. You can use the regular subtraction key or the minus key in parentheses—it doesn’t matter. To type, just pressx^{3}and then pressx3.

With App4Math, you can quickly change your answer to the form you want. Do you want to see a few more decimal places of your answer? Just press the right arrow a few times. Do you want to change the answer to a fraction? Just press **÷**. Or press MODE repeatedly to see all the possible forms of the answer, including:

- Decimal
- Improper Fraction
- Mixed Fraction
- Percentage
- Scientific Notation
- Quotient with Remainder
