Signed Number Comparison

← Back to Unit 1

Description

Compare how the same decimal value is represented in three different signed number systems. See why two's complement is the preferred method for modern computers.

Learning Objectives

Bloom Level: Analyze (L4)

After using this MicroSim, students will be able to:

• ✓ Compare sign-magnitude, one's complement, and two's complement
• ✓ Explain the "two zeros" problem in sign-magnitude and one's complement
• ✓ Justify why two's complement is preferred for arithmetic hardware

How to Use

1. Use the slider to select a value from -7 to +7
2. Observe how each representation encodes the same value
3. Compare the properties in the table below
