Tackle operations with integers, fractions, and decimals

In elementary and middle school you have probably been going over how integers, fractions and decimals work, but mainly doing hands-on activities. In high school, you will need to solve algebraic equations involving integers, fractions and decimals regularly and preferably fast. Therefore, knowing how to add, subtract, multiply and divide integers, fractions and decimals on paper/whiteboard/tablet is a very useful skill that will help you prepare for high school math and achieve much desired success up to the very last grade.

Integers are whole numbers, such as -5, 0, and 7. Fractions are numbers that represent a part of a whole, such as 1/2 or 3/4. Decimals are numbers that represent a part of a whole using a decimal point, such as 0.5 or 0.75.

To add or subtract integers, simply add or subtract the numbers. For example, -5 + 7 = 2 and 0 – 3 = -3.

To add or subtract fractions, you need to find a common denominator. The common denominator is the lowest common multiple of the denominators of the fractions. For example, the common denominator of 1/2 and 3/4 is 4. To add 1/2 and 3/4, you would first rewrite them as 2/4 and 3/4. Then, you would add the numerators and keep the denominator. So, 2/4 + 3/4 = 5/4, or 1 1/4.

To add or subtract decimals, simply line up the decimal points and add or subtract the numbers. For example, 0.5 + 0.75 = 1.25 and 2.3 – 1.5 = 0.8.

To multiply integers, simply multiply the numbers. For example, -5 x 7 = -35 and 0 x 3 = 0.

To multiply fractions, you would multiply the numerators and multiply the denominators. For example, 1/2 x 3/4 = 3/8.

To multiply decimals, you would multiply the numbers as if they were whole numbers, ignoring the decimal points. Then, you would count the total number of decimal places in the two numbers and place the decimal point in the answer so that there are that many decimal places. For example, 0.5 x 0.75 = 0.375.

To divide integers, you would use long division. For example, -5 ÷ 7 = -0.7142857143 and 0 ÷ 3 = 0.

To divide fractions, you would invert the divisor and multiply. For example, 1/2 ÷ 3/4 = 1/2 x 4/3 = 2/3.

To divide decimals, you would move the decimal point in the divisor to the right until it is a whole number. Then, you would move the decimal point in the dividend the same number of places to the right. Finally, you would divide the numbers as if they were whole numbers. For example, 0.5 ÷ 0.75 = 5 ÷ 7 = 0.7142857143.

 

Conquer algebra basics

In this section, we will delve into the captivating world of algebra, a branch of mathematics that deals with the study of variables and their intricate relationships. Algebra forms the very foundation of higher mathematics and is an essential tool for understanding and solving a wide range of real-world problems.

To conquer algebra basics, it is crucial to develop a solid understanding of algebraic expressions. These expressions are mathematical phrases that involve variables, numbers, and operations such as addition, subtraction, multiplication, and division. To manipulate algebraic expressions effectively, you must master the art of simplifying them, combining like terms, and expanding brackets. By simplifying expressions, you can make them easier to understand and work with.

Another fundamental concept in algebra is solving linear equations and inequalities. Linear equations are equations that involve variables to the power of one, while linear inequalities are inequalities that involve variables to the power of one. Solving linear equations and inequalities requires isolating the variable on one side of the equation or inequality sign. This can be achieved by applying various algebraic operations such as adding, subtracting, multiplying, or dividing both sides of the equation or inequality by the same number.

Graphing linear equations and inequalities is yet another important skill in algebra. A graph is a visual representation of an equation or inequality on a coordinate plane. Graphing linear equations and inequalities helps visualize the relationship between variables and understand the solutions to equations and inequalities. To graph a linear equation, you need to find the intercepts (where the line crosses the x-axis and y-axis) and then draw a straight line through the intercepts.

By mastering these fundamental concepts of algebra, you will lay a strong foundation for success in high school math. Remember, practice is key to mastering algebra. Regularly solving algebraic problems and challenging yourself with different types of equations and inequalities will help you develop the skills and confidence you need to excel in algebra and beyond.

 

Geometry: angles, lines, and shapes

This section will teach you about the basic concepts of geometry, including angles, lines, and shapes. You will learn to identify and classify different types of angles, understand the concept of parallel and perpendicular lines, memorize the properties of different polygons, and understand the concept of area and perimeter. You will also explore the concept of similarity and congruence, and how to identify similar and congruent geometric figures.

Angles are measured in degrees, and there are several types of angles, including acute angles (less than 90 degrees), right angles (90 degrees), obtuse angles (between 90 and 180 degrees), and straight angles (180 degrees).

Lines are either straight or curved, and they can be parallel, perpendicular, or intersecting. Parallel lines never meet, perpendicular lines intersect at right angles, and intersecting lines meet at any other angle.

Polygons are closed shapes with straight sides, and they are classified according to the number of sides they have. For example, a triangle has three sides, a quadrilateral has four sides, a pentagon has five sides, and so on.

The area of a polygon is the amount of space it encloses, and the perimeter of a polygon is the distance around its sides.

Similarity and congruence are important concepts in geometry. Similar figures have the same shape but not necessarily the same size, while congruent figures have the same size and shape.

 

Statistics: making sense of data

In this section, we will delve into the fascinating world of statistics, equipping you with the tools to make sense of data and draw meaningful conclusions. Statistics is a powerful discipline that enables us to analyze, interpret, and present data, transforming raw information into actionable insights.

To kick off our exploration, we will begin by understanding data sets. A data set is a collection of information, usually presented in a structured format. It can include numerical values, categorical data, or a combination of both. By examining data sets, we can identify patterns, trends, and relationships that would otherwise remain hidden.

Next, we will venture into the realm of graphs and charts. These visual representations of data allow us to see patterns and trends more easily. Bar charts, line graphs, histograms, and scatterplots are just a few examples of the many graphical tools at our disposal. Each type of graph serves a specific purpose, and choosing the right one is crucial for effectively communicating your findings.

Moving on, we will explore the concept of probability. Probability deals with the likelihood of an event occurring. It helps us quantify uncertainty and make predictions based on past observations. From flipping a coin to predicting weather patterns, probability plays a vital role in various fields.

Finally, we will delve into the art of drawing conclusions from data analysis. This involves interpreting the patterns, trends, and relationships we have uncovered. By applying statistical techniques and critical thinking, we can make informed decisions and take appropriate actions based on our findings.

Remember, statistics is not just about numbers; it’s about understanding the world around us and making better decisions. By mastering the basics of statistics, you will gain a valuable skill that will serve you well in high school math and beyond.
