In this video we are going to look at how to do calculations with standard form.



When adding and subtracting numbers in standard form, we need to write the numbers out into ordinary numbers, do the sum and then turn the...

You should already know that velocity-time graphs look like this... and how we can use them to map out a journey.



If you’re unsure, you may want to watch this video first...In this video we’re going to look...

Learn how to convert between rectangular and polar equations. A rectangular equation is an equation having the variables x and y which can be graphed in the rectangular cartesian plane. A polar equation is an equation defining an...

In this video, you will learn how to find the multiplicative inverse of a number and use it to write equivalent expressions. The multiplicative inverse, also known as the reciprocal, is the number that, when multiplied by the original...

In this video, we are going to learn about volume of prisms, and how to calculate it. To start, we talk about length, and area. Length measures across one dimension and so is usually measured in cm or m. Area measures across two...

In this video lesson, students learn how to solve mixed number multiplication problems using pictures and the standard algorithm. They are reminded of key concepts such as multiplication as equal groups, algorithms for multiplying whole...

In this video, the teacher explains how to identify the zeros of a quadratic function that is a difference of two squares by factoring. They provide examples and explain the concept of zeros being the input values that make the function...

👉 Learn how to write the rule of a sequence given a sequence of numbers. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. To write the explicit formula of...

👉 Learn how to evaluate the integral of a function. The integral, also called antiderivative, of a function, is the reverse process of differentiation. Integral of a function can be evaluated as indefinite integral or as a definite...

Learn how to add/subtract vectors. Vectors can be added, subtracted and multiplied. To add or subtract two or more vectors, we simply add each of the corresponding components of the vectors.

👉 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...

Scientific notation allows us to more easily express very large or very small numbers encountered in engineering and science. Using exponents, we can convert standard decimal numbers into scientific notation and vice versa.

In this video we will learn about the Relationship Between Zeroes And Coefficient of Polynomials. This video will cover topics such has General form, Sum of Zeroes, Product of Zeroes, Sum of product of Zeroes and solve some problems .

In this video, the teacher explains how to evaluate expressions by interpreting parentheses as "do this first." The examples provided involve multiplication, subtraction, and addition, and the teacher emphasizes the importance of...

This video is a review of basic arithmetic for the purpose of solving problems on the quantitative reasoning section of the GRE revised General Test. This video covers the basics of fractions. Topic covered: division of fractions,...

In this lesson, students will learn how to solve equations with variables and parameters represented by letters. They will understand the concept of additive and multiplicative inverses and how to use them to isolate the variable and...

👉 Learn how to expand a binomial using binomial expansion. A binomial expression is an algebraic expression with two terms. When a binomial expression is raised to a positive integer exponent, we usually use the binomial expansion...

Algebraic fractions are simply fractions with algebraic expressions either on the top, bottom or both. We treat them in the same way as we would numerical fractions. In part 1 we saw how to simplify, and add and subtract algebraic...

👉 Learn how to condense logarithmic expressions. A logarithmic expression is an expression having logarithms in it. To condense logarithmic expressions means to use the logarithm laws to reduce logarithm expressions from the expanded...
