👉 Learn how to convert numbers to scientific notations. Scientific notation is a convenient way of writing very large or very small numbers. A number written in scientific notation is of the form a * 10^n where a is the first non-zero...

👉Learn how to solve a system (of equations) by elimination. A system of equations is a set of equations which are collectively satisfied by one solution of the variables. The elimination method of solving a system of equations involves...

In this video, the teacher explains how to efficiently solve decimal operations in real-world problems using standard algorithms. The example given is finding the number of weeks it would take to save half of a weekly allowance to buy a...

In this video, the teacher explains how to convert fractions into decimals using long division. They provide examples of fractions like 3/4 and 2/5 and demonstrate the step-by-step process of converting them into decimals.

👉 Learn how to find the first five terms of a sequence. Given an explicit formula for a sequence, we can find the nth term of the sequence by plugging the term number of the sequence for n in the given formula. When n = 1, 2, . . ., 5...

👉 Learn how to graph quadratics in standard form. A quadratic equation is an equation whose highest exponent in the variable(s) is 2. To graph a quadratic equation, we make use of a table of values and the fact that the graph of a...

To what number is it possible to count? Is there a greater number than all, or does the account never end and is infinite? What is the largest number that anyone could have imagined? The concept of the largest number can be a bit...

👉 Learn how to solve for the length of the sides and the measures of the angles of a triangle using the law of sines. The law of sines is used in determining the length of the opposite side to a known angle measure or the measure of the...

👉 Learn how to solve two step linear equations. A linear equation is an equation whose highest exponent on its variable(s) is 1. To solve for a variable in a two step linear equation, we first isolate the variable by using inverse...

👉 Learn about the special right triangles. A special right triangle is a right triangle having angles of 30, 60, 90, or 45, 45, 90. Knowledge of the ratio of the length of sides of a special right triangle enables us to solve for any...

👉 Learn how to identify the vertex of a parabola by completing the square. A parabola is the shape of the graph of a quadratic equation. A quadratic equation can be written in the standard form (i.e. in the form y = ax^2 + bx + c) or it...

In this lesson, students learn how to subtract decimals using base 10 blocks. They review how base 10 blocks can represent whole numbers and then extend that understanding to represent decimals. By using smart estimates and visual...

In this video series I show you how to graph and order numbers. It is important when graphing and ordering numbers that we have all of our numbers simplified and written in the same form. We then can arrange the numbers from least to...

👉 Learn all about angles of trigonometry. In this playlist, we will explore what makes up an angle and how to graph an angle in degrees or radians to determine the quadrant. We will then take a look at angle relationships such as...

👉 Learn how to solve compound inequalities and graph their solution on a number line. A compound inequality is an inequality having more than 1 inequality sign. To solve compound inequalities, we use inverse operations, applying the...

In this video, the teacher explains how to round decimals to the nearest whole number using a number line. They demonstrate the process step by step, showing how to determine whether a decimal is closer to the whole number before or...

In this Microsoft Excel tutorial, we learn how to present numeric data in various formats such as general, numbers, currency, accounting, date, time, percentage, fraction, scientific, and text. The tutorial also introduces basic...

👉 Learn all about the trigonometry of right triangles. A right triangle is a triangle that has 90 degrees as one of its angles. The trigonometric identities of right triangles give us the relationship between the angles of a right...

👉 Learn how to solve the word problems with trigonometry. Word problems involving angles, including but not limited to: bearings, angle of elevations and depressions, triangles problems etc are solved using trigonometry. To be able to...

Learn quick ways of comparing two decimal numbers without using a place-value chart!

In this video we go over parts of a degree, and congruent angles.
