*Yet this time, build the circle and plot this point so that no two digits have the same absolute value. (Ex: You can't use both 3 and -3).

In the app below, the green check mark indicates no two values have the same absolute value.

In the app below, the green check mark indicates no two values have the same absolute value.

In the app below, the red "X" indicates at least two values have the same absolute value.

In the app below, the red "X" indicates at least two values have the same absolute value.

Use the drop down lists to change the values of the digits. Once you complete a successful setup, you'll know.

Demonstrate how you know your setup (in the app above) is correct.

Create another valid setup that is different from the one you created above.

Demonstrate how you know your setup (in the app above) is correct.
