Lesson12: Equations With Multiplication And Division
Lesson11: Equations With Addition And Subtraction
Lesson9: Write Expressions With Fractions
Lesson7: Write Multiplication And Division Expressions
Lesson6: Write Addition And Subtraction
Lesson5: Evaluate Expressions With Fractions
Lesson4: Use The Distributive Property To evaluate Expressions
The distributive property gives you another way to evaluate a number multiplied by a sum or a difference.
Lesson3: Order Of Operations
The operations are addition, subtraction, multiplication, division, exponentiation, and grouping; the order of these operations states which operations take precedence before which other operations.
Lesson2: Use multiplicaion properties to evaluate expressions
Associative Property, Commutative Property, Identity Property, Zero Property
Lesson1: Use addition properties to evaluate expressions
A rational number is any number that can be expressed as a ratio of two integers (hence the name "rational").
Lesson 6: Divide Integers
Division of integers is the opposite operation ofmultiplying integers It is the process by which one is trying to determine how many times a number is contained into another.
Lesson 5: Multiply Integers
Multiplying integers is just like the multiplication of whole numbers, except that with integers, you have to keep tract of your signs.
Lesson 4: Subtracting Integers
To subtract integers, change the sign on the integer that is to be subtracted.
Lesson 3: Adding Integers
When adding integers with signs that are the same, ADD the numbers and keep the sign.
If we compare numbers with different signs, then negative number is less than positive. If numbers are both positive then this is the case when we compare whole numbers. Ifnumbers are both negative then we compare numbers without signs. The bigger positive number, the smaller negative.
Step 1: Write the mixed numbers as improper fractions. Step 2: Rewrite the division problem using the improper fractions. So to divide mixed numbers you should change the fractions to improper fraction and the convert the problem to a multiplication question.
Lesson 8: Divide Whole Numbers and Fraction
Multiply the bottom number of the fraction by the whole number
Multiply the numerators of the fractions to get the new numerator.
Multiply the denominators of the fractions to get the new denominator.
Lesson 4 : Subtract Fractions and Mixed Numbers with Unlike Denominators
Keep the denominator the same.
Add or subtract the numerators.
Find the Lowest Common Multiple (LCM) between the denominators.
Convert all mixed numbers into improper fractions.
In this second method, we will break the mixed number into wholes and parts.
Thus, is equivalent to.
Lesson 3 : Adding Fractions and Mixed Numbers with Unlike Denominators
Keep the denominator the same.
Add or subtract the numerators.
Find the Lowest Common Multiple (LCM) between the denominators.
Convert all mixed numbers into improper fractions.
In this second method, we will break the mixed number into wholes and parts.
Lesson 2 : Subtract Fractions and Mixed Numbers with Like Denominators
Subtracting mixed numbers with like denominators. Think of a mixed numbersas a number and a fraction. You can subtract numbers.
Lesson 1 : Add Fractions and Mixed Numbers with Like Denominators
Add the numerators of the two fractions.
Place that sum over the common denominator.
If this fraction is improper (numerator larger than or equal to the denominator) then convert it to a mixed number.
Add the integer portions of the two mixed numbers.

Lesson 11: Terminating and Repeating Fraction
Terminating and Repeating Decimals. Any rational number (that is, a fraction in lowest terms) can be written as either a terminating decimal or a repeating decimal . Just divide the numerator by the denominator .
Lesson 10: Fractions,Mixed Numbers, and Decimals
A mixed number is a whole number plus a fraction. To find the decimal form of a fraction just divide the numerator by the denominator using a calculator or long division. Then add the decimal number to the whole number.
Lesson 9: Compare and Order Fraction
To compare fractions, you must first change them so they have the same denominator.
Lesson 8: Simplest Form
Simplest form of a fraction. A fraction whose numerator and denominator have the number 1 as the only common factor.
Lesson 7: Equivalent Fractions
Equivalent fractions fractions that show different number with the same value.
Lesson 6: Least Common Multiple
Least common multiple. The least number that is a multiple of two or more numbers.
Lesson 5:Greatest Common Factor
the greatest common factor is sometimes called the greatest common divisor. (GCF)
Lesson 4: Divisibility Rules
Lesson 3: Prime Factorization
A prime factorization expresses a composite number as a product of prime factors.
Lesson 2:Exponents
An exponents refers to the number of times a number is multiplied by itself.
Lesson 1: Factors and Prime Numbers
A prime number is a whole number with exactly two factors, 1 and the number itself.
