This family view narrows the full math map to one connected cluster. Read it from left to right: earlier nodes support later ones, and dense middle sections usually mark the concepts that hold the largest share of future work together.
Use the graph to plan review, then use the full concept list below to open precise pages for definitions, examples, formulas, and related mistake guides. That combination keeps the page useful for both human study flow and crawlable internal linking.

Rounding
Replacing a number with a nearby simpler approximation at a specified place value, using the digit to the right to decide.
Precision
The degree of exactness in a measurement or calculation, reflected in the number of significant digits reported.
Approximation
A value intentionally chosen to be close to but not exactly equal to the true value, with a known or estimated error.
Significant Figures
Significant figures are the meaningful digits in a measured quantity, reflecting its precision.
