Congruence Calculations
The { CON } selection from the NUMBER THEORY menu lets you perform congruence calculations. Given a, b, and m, the program searches for all values of x such that ax is congruent to b for modulus m.
Performing Congruence Calculations
To perform a congruence calculation:- Select { NUM } from the
MATHEMATICS menu.
The calculator displays the NUMBER THEORY menu. - Select { CON } from the menu.
The calculator displays:
- Enter the values of a, b, and m, pressing the applicable key after each value.
- Press { EOD } to continue with the program and
perform the calculation.
• If there is no solution, the message NO SOLUTION is displayed.
• If there are solutions, the value of x for the first solution is displayed.
for example. - Press { NXT } repeatedly to display the
remaining solutions for which x ≼ m.
When all the solutions have been displayed, pressing { NXT } returns you to the CONGRUENCE menu.
