The problem with algebra is that it isn’t a simple tangible object…like a spoon. If it was, it’d be easy to explain. After all, few people who manage to eat lunch with a spoon will have trouble explaining how it works afterwards. But, unfortunately, that’s just not what algebra ...

Using y to replace the unknown number, the problem "four times a number minus three is equal to 21" becomes y × 4 - 3 = 21.Algebra gives the flexibility to replace unknowns with symbols and work around them. In the simplest term, algebra is like a tool for thinking logically and so...
What is Algebra? Algebra helps solve the mathematical equations and allows to derive unknown quantities, like the bank interest, proportions, percentages. We can use the variables in the algebra to represent the unknown quantities that are coupled in such a way as to rewrite the equations. ...
What Is Algebra? Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols. In elementary algebra, those symbols (today written as Latin and Greek letters) represent quantities without fixed values, known as variables. Just as sentences describe ...
Some facts about Algebra Algebra is derived from the Arabic word Al-jabr, which means the reunion of broken parts. Until the 16th century, there were only two subfields of mathematics: geometry and arithmetic. Fields, rings, and groups of abstractions are all studied as part of algebraic studi...
You don’t need pictures to do algebra. What you need is a way to use the operations that you already know (addition, subtraction, multiplication, and division) to solve equations. The tricky part? You must preserve the equality. Equality means the same. When you do something to one side...
The procedure is then written like this: x = [ √(4∙B + A2) + A ]/2 y = [ √(4∙B + A2) - A ]/2 This is a variation of the quadratic formula. Similar procedures appear as far back as Babylonia, and represented the state of algebra (and its close ties to astronomy)...
