When you multiply numbers together, you’re looking at how many groups of, or lots of, something you have. You can use this same thinking, when you are multiplying fractions. For example: ( \frac{2}{3 ...

The method to divide fractions is to keep the first fraction the same, turn the divide sign into a multiply and turn the second fraction upside down. This is known as multiplying by the reciprocal.
Elementary algebra, also called school algebra, college algebra, and classical algebra, [22] is the oldest and most basic form of algebra. It is a generalization of arithmetic that relies on variables and examines how mathematical statements may be transformed.
Algebra is great fun - we get to solve puzzles! What is the missing number? OK, the answer is 6, right? Because 6 − 2 = 4. Easy stuff. Well, in Algebra we don't use blank boxes, we use a letter (usually an x or y, but any letter is fine). So we write: It is really that simple.
The Algebra 1 course, often taught in the 9th grade, covers Linear equations, inequalities, functions, and graphs; Systems of equations and inequalities; Extension of the concept of a function; Exponential models; and Quadratic equations, functions, and graphs.
Algebra deals with Arithmetical operations and formal manipulations to abstract symbols rather than specific numbers. Understand Algebra with Definition, Examples, FAQs, and more.
Algebra - What is Algebra? | Basic Algebra | Definition | Meaning, Examples
Algebra is the branch of mathematics in which abstract symbols, rather than numbers, are manipulated or operated with arithmetic. For example, x + y = z or b - 2 = 5 are algebraic equations, but 2 + 3 = 5 and 73 * 46 = 3,358 are not.
