In the MathPrint™ mode, you can enter up to four levels of consecutive nested functions and expressions, which include fractions, square roots, exponents with ^, xÑ, and x When you calculate an entry on the Home screen, depending upon space, the answer is displayed either directly to the right of the entry or on the right side of the next line.

• ### Page 5: Modes

Modes Use q to choose modes. Press \$ # ! " to choose a mode, and < to select it. Press - or %s to return to the Home screen and perform your work using the chosen mode settings. Default settings are shown. DEG RAD Sets the angle mode to degrees or radians.

• ### Page 6

MATHPRINT mode displays most inputs and outputs in textbook format. Choose the MathPrint™ mode for better visual confirmation that math expressions have been entered correctly and to better reinforce the correct math notation. Note: Switching the mode between Classic and MathPrint clears calculator history and the stored operations (op1 or op2) value.

Exponentiation (^) and roots ( Ñ). Note: In Classic mode, exponentiation using G is evaluated from left to right. The expression 2^3^2 is evaluated as (2^3)^2, with a result of 64. In MathPrint™ mode, exponentiation using G is evaluated from right to left. The expression 2^3^2 is evaluated as 2^(3^2), with a result of 512.

%i %Y 60 < 17589 seconds equals 4 hours, 53 minutes, and 9 seconds. Fractions In the MathPrint™ mode, fractions with P can include operation keys (T, V, etc.) and most function keys (F, _, etc.). In Classic mode, fractions with P do not allow operation keys, functions, or complex fractions in the numerator or denominator.
