Fractions represent parts of a whole. Equivalent fractions have the same value even if they are written differently. A mixed number consists of a whole number and a fraction. A proper fraction has a numerator smaller than its denominator, while an improper fraction has a numerator equal to or greater than its denominator. Improper fractions can be changed into mixed numbers, and fractions with a common denominator can be added or subtracted.

Fractions
A fraction represents a numerical quantity that is not a whole number. It consists of a numerator above a denominator. The key parts are multiplying and dividing fractions by multiplying or dividing the numerators and denominators respectively. When adding or subtracting fractions, the first step is to find the least common denominator (LCD) so the fractions have a common bottom term, then only the numerators are added or subtracted. This process can also be done with variables as the numerator and denominator terms.

Chapter 1 Directed Numbers
Numbers to the left of zero on a number line are negative, while numbers to the right are positive. Negative numbers multiplied together are positive, while a negative number multiplied by a positive number or vice versa results in a negative product. Division follows similar rules, with a negative number divided by a positive resulting in a negative quotient. When combining operations, calculations in brackets are performed first, followed by multiplication/division from left to right, and finally addition/subtraction from left to right.
Chapter 1 Whole Numbers
Whole numbers are used for counting objects and each digit has a place value and digit value. For example, in the number 3468279, the 9 represents 9 ones, the 7 represents 70 tens, and so on. Rounding off a number gives its approximate value by observing the digit to the right and adjusting the digit being rounded based on whether its value is above or below 5. Calculations with whole numbers follow the order of operations, starting with anything in brackets, then multiplication/division from left to right, and finally addition/subtraction from left to right.
Chapter 3 Fractions
Fractions can be represented as parts of a whole or as ratios of two numbers. Equivalent fractions have the same value even if represented differently. A mixed number consists of a whole number and a fraction part. A proper fraction has a numerator smaller than the denominator, while an improper fraction has a numerator equal to or greater than the denominator. Improper fractions can be converted to mixed numbers. Addition and subtraction of fractions is done with common denominators.
