Working with Rational Numbers

Working with Rational Numbers

When students use Rational Numbers, they can perform addition, subtraction, multiplication and division involving any type of rational number. It helps prepare you for more advanced math and supports the ability to tackle practical and multi-part problems with different numbers.

Integers

Students learn how to do all basic calculations using whole numbers (with or without a minus sign). They study how numbers are involved in temperatures, elevations and finances. Working on integers provides an opportunity for students to understand the connections between numbers and prepares them for algebra. Learning becomes enjoyable and useful when real-life situations and number lines are involved.

Decimals

Students gain the ability to add, subtract, multiply and divide numbers with decimals. Among other things, this requires lining up the decimal points and recognizing place value. Understanding decimals is necessary when budgeting and working in science and measurements. Students work on exercise involving money and data analyzing to improve their practical math skills.

Fractions

While in this section, students also work with fractions and mixed numbers, performing operations and multiplying and dividing them. To work with ratios, proportions and algebraic expressions, you must understand fraction operations. Using pictures and instructions encourages learners to improve both their confidence and accuracy.

Negatives

Individuals examine ways to use negative numbers in all kinds of calculations. They learn to combine different signs and realize debts, temperatures and timelines are used in real life. Using negative values helps in your understanding of algebra, graphing and interpreting data.
