Verify Mode

The verify mode enables students to develop mathematical concepts, for example order of operations,

manipulating inequalities and checking exact trigonometric values. This use of this mode is further

illustrated in the accompanying teaching and learning activities.

Mode: 3 VERIF

Method: Input the left hand side of the expression then use the ’verify’ button to enter an equal or

inequality sign. Enter the right hand side of the statement and press equal. The calculator will display

either TRUE or FALSE.

Example

To assess the validity of the statement 5 + 2 × 3 = 21 press 5+2O3q 6121=.

Other VERIF examples include:

1 2 ... 10 11 12 13 14 15 16 17 18 19 20 ... 23 24
