Common Core Math: High School Number & Quantity: Real Numbers

The real number system, often denoted , contains whole numbers, negative numbers, fractions and everything in between. Real numbers can be separated into two distinct sets: rational numbers and irrational numbers. Rational numbers are numbers that can be written as ratios of integers (such as -7, 42, 3/4 and 99/100). Irrational numbers are real numbers that are not rational numbers (such as π and 2). In high school, students combine rational and irrational numbers with arithmetic operations and exponents.
