Whether you're just starting out, or need a quick refresher, this is the video for you! Mrs. C will go show you step-by-step how to factor an algebraic expression, using different methods and several examples.

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.

Welcome to How to Factor out a Coefficient with Mrs. C.! If you need help understanding how to factor out a coefficient from an algebraic expression, we're here to help you out! Whether you're just starting out, or need a quick...

The building blocks of all natural numbers are the prime numbers. The early Greeks invented the system still used today for separating natural numbers into prime and composite numbers.

Our modern decimal number system is base-10. Other number systems used in fields like computer engineering are base-2 (binary), base-8 (octal) and base-16 (hexadecimal).

Number systems evolved from the natural "counting" numbers, to whole numbers (with the addition of zero), to integers (with the addition of negative numbers), and beyond. These number systems are easily understood using the number line.

When working with fractions, division can be converted to multiplication by the divisor's reciprocal. This chapter explains why.

Sometimes arithmetic operations result in fractions greater than one, called "improper" fractions. An improper fraction can be converted into a "mixed number" composed of an integer plus a "proper" fraction.

Exponential expressions with divided terms can be simplified using the rules for subtracting exponents.

Any fraction can be converted into an equivalent decimal number with a sequence of digits after the decimal point, which either repeats or terminates. The reason can be understood by close examination of the number line.

Sometimes when finding a common denominator we create an unnecessarily large common denominator. This chapter explains how to find the smallest possible common denominator.

Integer exponents greater than one represent the number of copies of the base which are multiplied together. But what if the exponent is one, zero or negative? Using the rules of adding and subtracting exponents, we can see what the...

Radical expressions can often be simplified by moving factors which are perfect roots out from under the radical sign.

The commutative property is common to the operations of both addition and multiplication and is an important property of many mathematical systems.

Exponential expressions with multiplied terms can be simplified using the rules for adding exponents.

Decimal numbers with a finite number of digits after the decimal point can be easily converted into fractions. This chapter explains why.

A look at the logic behind the associative and distributive properties of multiplication.

Exponents can not only be integers and unit fractions. An exponent can be any rational number expressed as the quotient of two integers.

A humorous look at early attempts at creating number systems, leading up to our modern base-10 decimal number system which uses "positional notation". The story takes place on the fictitious island of Cocoloco.

There are an infinite number of rational numbers, but there are infinitely more irrational numbers. Neither type of number can represent every type of numeric quantity. By combining the rational and irrational numbers into the real...

A look behind the fundamental properties of the most basic arithmetic operation, addition.

The process of reducing any fraction to its simplest possible form is easily visualized using the number line.
