Computation and magnitude

Computation and magnitude provides the tools we need to compare, measure, and comprehend quantities in a meaningful way.

• Percentages allow us to discuss increases and decreases succinctly, making them indispensable in areas such as finance and statistics.
• Ratios allow us to compare quantities, whether we’re analysing recipes in a kitchen or resource distribution in large-scale projects.
• Scientific notation and significant figures provide both precision and clarity, especially crucial when handling extremely large or small values in fields like physics or engineering.
• Logarithms and orders of magnitude are essential for displaying and comparing values across vastly different scales.

Together, these tools allow us to differentiate and interpret numbers and relationships between values across a variety of contexts.

This resource revises Computation and Magnitude and within Computation and Magnitude there are 4 key concepts:

• Percentages and percentage increase/decrease
• Ratios
• Scientific notation and significant figures
• Logarithms and orders of magnitude
