# CRM.NR.2: Exact and Approximate Calculations

Utilize exact and approximate calculations to quantify real-world phenomena and solve problems.

- Subject: Mathematics
- Appears in: High School, https://georgiahomeroom.org/standards/math/high-school.md

## Expectations

- **CRM.NR.2.1**: Through multi-step/multi-operational problems, perform mathematical operations on real numbers demonstrating fluency using the order of operations.
- **CRM.NR.2.2**: Represent and solve problems using proportional reasoning with ratios, rates, proportions, and scaling.
- **CRM.NR.2.3**: Apply the rules of exponents to simplify numerical expressions, extending the properties of exponents to rational exponents.
- **CRM.NR.2.4**: Perform mathematical operations on real numbers to include numerical radical expressions and complex fractions.
- **CRM.NR.2.5**: Estimate solutions to problems with real numbers and use the estimates to assess the reasonableness of results in the context of the problem.
