Students test their skill at converting binary numbers to decimal numbers. Immediate feedback is provided.

Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.

Students read how to organize their work when multiplying more than two signed numbers. A review and practice problems complete the activity.

Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.

Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.

Students read the rules used in multiplying and dividing signed numbers. They view examples and work practice problems.

Students read an explanation of the Voltage Divider Rule with complex numbers. Examples are given.

Students read about the three categories of interest groups: Economic, grass roots and community-based, and civil and constitutional rights.

Students read about the different kinds of economic interest groups including business and trade associations, labor unions, agricultural organizations, and professional associations.

Learners use this interactive and animated object to examine the use of binary numbers in a programmable logic controller. A brief quiz completes the activity.

This primer introduces the student to the correct method of entering complex numbers into a TI-86 calculator.

Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.

Students read an explanation of "superposition" as a technique for ac circuit analysis. Complex numbers are used.

Students view a demonstration of the Current Divider Rule with the use of complex numbers. Examples are given.

Learners study the types of information letters and numbers placed inside general piping and instrumentation diagram symbols.

Learners examine how metal detectors function. This object includes animation and sound.

Students read about the different kinds of civil/constitutional rights interest groups and answer multiple-choice questions.

Learners follow the steps for adding and subtracting signed numbers and complete practice exercises.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

In this learning activity you'll review an explanation of scientific notation and complete exercises to convert scientific notation to ordinary numbers.
