Learners use the Base Minus One Complement method to do octal subtraction.

In this highly interactive and animated object, learners follow a step-by-step process to reduce algebraic fractions, which contain no addition or subtraction, to their simplest, most elementary form. Immediate feedback is provided. This activity has audio content.

In this learning activity you'll apply the Law of Sines in the solution on an oblique triangle when provided with two angles and the side opposite one of the angles.

Learners examine two methods for converting an octal number to a decimal number. Exercises are provided at the end of the learning object.

In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
