Ordre de Grandeur (Thomson TO)

Ordre de Grandeur teaches students how to determine orders of magnitude from the results of multiplications. It was bundled alongside similar educational programs teaching numbers and mathematical operations.

Commented-Out Line#

The TO9/TO8/TO9+ disk version from the Logiciels Nathan Ecoles : Mathématiques compilation has a commented-out line at 870 of ORDGRAND.BAS. It is not present in any of the tape releases, including for the MO series.

' COLOR4,0:FY=20:GOSUB4650

Uncommenting this line makes a blue arrow appear in the main menu. It is purely decorative; tapping on it using the light pen or pressing Right does not do anything.
