How do I input numbers and variables in the Advanced mode?

Basic input rules for whole numbers, fractions, mixed numbers, and decimals.

To enter numbers, use the number entry keys, including "." for decimals and "/" and "_" for fractions.

In some cases, negative values should be entered in parentheses. Example: 2x*(-4_5/8), 2 + 7.2*(-5x).

Whole numbers.
To input whole numbers, use the corresponding number entry keys on the calculator keyboard.

Fractions are typed using fraction bar as the fraction bar.

So, "two-thirds" would be typed as 2/3.

"One-half" would be typed as 1/2.

Fractions can be entered with or without parentheses.

Mixed fractions
Separator symbol is used to separate the whole number and the fraction.

So, "three and one half" would be typed as 3_1/2.

Decimal numbers
Use a decimal point to separate the whole part from the decimal part (ex. 12.34, 0.4 or .4).
