Whole numbers- Properties of numbers and calculations using whole numbers
In this lesson, you will learn how numbers are very important as we always use them in our lives and without numbers, there is no math. By the end of this lesson, you will be able to define and distinguish the properties of natural numbers, whole numbers, integers, and rational and irrational.
In this lesson, you will learn how numbers can be divided and have no remainders, you will be able to define a factor and a multiple of a number and determine the highest common factors and the lowest common multiple and solve for ratios and rates.
In this lesson, you will learn about ratios and compare two qualities with the same units, to ensure all the units are the same we must divide each part of the ratio with the highest common factor. At the end of this lesson, you will know how to solve problems for ratios, rates and proportions.
In this lesson, you will learn about how integers are important for the topics that will be covered later such as algebraic expressions, equations, finance and graphing. By the end of this lesson, you will be able to add, subtract, multiply and perform calculations involving all four operations ...
In this lesson, we will learn about how calculations involving all four operations with numbers that involve squares, cubes, square roots and cube roots of integers you need to practice as many examples as possible with this lesson you will be able to solve these sums.
Exponents Part 2: Exponential equations and Scientific Notation
In this lesson, you will learn about exponents that are useful to describe very large and small numbers. This lesson will detail how to perform calculations using exponential laws and teach you a new concept of scientific notation that represents small or large numbers into simple decimal numbers...
Arithmetic Patterns - Determining Rule in Words and Formulae
In this lesson, you will learn about Arithmetic sequences. Arithmetic sequences are when the difference between two successive terms is common and we subtract successive terms to determine whether the sequence is arithmetic, this teaches you the general formula or rule of a sequence.
Geometric Patterns - Determining Rule in Words and Formulae
In this lesson, we will learn about how a pattern or sequence is an arrangement of objects or numbers in a specified order. This lesson will help you calculate the term number and the number of terms in a geometric sequence and determine the general formulae of a geometric sequence.
