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.

Learners are introduced to the binary-coded decimal, a common way of encoding decimal digits in computing and electronic systems. A brief quiz completes the activity.

The learner will evaluate powers of 10 with integer exponents and multiply decimal numbers by powers of 10 with integer exponents.

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

In this learning activity you'll practice calculating the between the binary number system and the decimal number system.

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.

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.

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

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.
