MANSIMP mode lets you simplify fractions manually.
MANSIMP was designed for teaching and learning fractions
concepts. In MANSIMP mode, you can simplify fractions and
the results of expressions using fractions, step-by-step.
When a fraction result is not expressed in its lowest terms, a
down arrow (ï) is displayed to remind you that you can
simplify the result. Use úSIMP from the FRACTION menu to
simplify the fraction. You can then use úbºc or úaÀbºc to
change the display format of the fraction result.
Typically, you use the MANSIMP simplification mode with the
úaÀbºc display format mode for teaching or learning fraction
concepts. The display format of fraction results can vary when
you are using MANSIMP and úaÀbºc.
¦When you simply enter a fraction and press ¸, the
format in which you entered the fraction is preserved.
¦When you add or subtract using a mixed fraction,
calculation takes place on the whole-number and
fractional part of the mixed-fraction separately. The result
is displayed as a mixed fraction.
¦When you multiply or divide using a mixed fraction, the
result is displayed as a simple fraction.
