Algebra
Complex numbers, simplify expressions and more.
| Arithmetic and Geometric Sequences | An arithmetic sequence is a sequence in which the difference between any two numbers is a constant. A geometric sequence is a sequence in which when any two consecutive numbers are divided, the quotient is a constant. This page will allow you to investigate a geometric sequence or an arithmetic sequence. |
| Factorials | The factorial of a number is the product of all numbers from one to that number. This page will help you find the factorial of any number. |
| Factors and Multiples | Do you need to find the Greatest Common Factor (GCF) or the Least Common Multiple (LCM) of set of numbers or algebraic expressions? This page can help. |
| Fibonacci Sequences | In a Fibonacci sequence, the next term is the sum of the previous two terms. Learn the first 20 terms of the Fibonacci sequence and also about the Fibonacci sequence seen in nature. |
| Graphs and Plots | Have a set of data that you want to display in a graph? You can use this page to display a data set in a picture graph, a bar graph, a line graph, a pie chart, a scatter plot, or a box and whisker plot. |
| Order of Operations | A mathematical operation with more than one operation is solved using order of operations. Learn how to solve an expression using the correct order of operations. |
| Prime Numbers and Prime Factorization | Prime factorization of a number is factoring it such that all its factors are prime numbers. This page will show you how to find the prime factorization of a number. |
| Simplifying Algebraic Expressions | An algebraic expression can be solved using the associative, commutative, and distributive properties. This page will show you the property used to simplify an algebraic expression. |
| Statistical Measures | Different statistical measures can be calculated for a data set. Use this page to calculate measures of central tendency, standard deviation, or best fit line for a data set. |
| Adding Complex Numbers | Complex numbers have real and imaginary parts. This page will help you add two such numbers together. When you type in your problem, use "i" to mean the imaginary part. Here are some examples you can try: (3+4i)+(8-11i) 8i+(11-12i) 2i+3 + 4i |
| Subtracting Complex Numbers | Complex numbers have real and imaginary parts. This page will show you how to subtract such numbers. Here are some examples of what you would type: (3i+1)-(5+2i) (-1-5i)-(10+12i) i-(5-2i) |
| Multiplying Complex Numbers | Complex numbers have real and imaginary parts. This page will show you how to correctly multiply them together. Here is an example of what you would type: (3i+1)(5+2i) |
| Dividing Complex Numbers | Type in any sort of expression here, involving complex or imaginary numbers. When you click the button, this page will try to simplify/calculate it for you. Ex. 3i-4+10i-(3+4i)(9-2i)-14i |
| Variables and Complex Numbers | A basic premise of algebra is that a letter (or variable) can be put where a number is supposed to go. This page will show you how to perform basic mathematical operations on expressions that involve variables. To use this page, type your expression that contains variables into the first box below. For any variables, fill in their values into one of the 26 smaller boxes. Click "Number Crunch" to see how to find the single value for the expression. |
| Adding and Subtracting Polynomials | This page will show you how to add and/or subtract polynomials. (3x^2+4x-2) + (-7x^2-10x+17) |
| Simplifying Expressions: Powers | Algebraic expression frequently involve terms that have exponents. In some cases, these terms have to be multiplied together. This page will show you how to handle exponents when multiplication is involved. Ex. yy^2 |
| Simplifying Expressions: Products | This page will show you how to simplify an algebraic term that involves products. Products mean the terms only involve multiplication. Ex. (3a^2)(6a^5) |
| Simplifying Expressions: Like Terms | This page will show you how to simplify an algebraic term that involves products. Products mean the terms only involve multiplication. Here are some examples you could try: (3a^2)(6a^5) 3x-2y-3x |
| Power of i | Calculate and power of i(the square root of -1.) This page will show you how to raise i to and power. Enter your number in the sin box provided and click “Do It!” |
