The sum of 7 and 11 is If the product of a number and —7 is reduced by 3, the resulting number is 33 less than twice the opposite of that number. What is the number?

It is taught to students who are presumed to have no knowledge of mathematics beyond the basic principles of arithmetic. In algebra, numbers are often represented by symbols called variables such as a, n, x, y or z. This is useful because: It allows the reference to "unknown" numbers, the formulation of equations and the study of how to solve these.

This step leads word problem algebra 1 the conclusion that it is not the nature of the specific numbers that allows us to solve it, but that of the operations involved. It allows the formulation of functional relationships.

Polynomial A polynomial is an expression that is the sum of a finite number of non-zero termseach term consisting of the product of a constant and a finite number of variables raised to whole number powers.

A polynomial expression is an expression that may be rewritten as a polynomial, by using commutativity, associativity and distributivity of addition and multiplication. A polynomial function is a function that is defined by a polynomial, or, equivalently, by a polynomial expression.

The two preceding examples define the same polynomial function. Two important and related problems in algebra are the factorization of polynomialsthat is, expressing a given polynomial as a product of other polynomials that can not be factored any further, and the computation of polynomial greatest common divisors.

A related class of problems is finding algebraic expressions for the roots of a polynomial in a single variable. Abstract algebra Main articles: Abstract algebra and Algebraic structure Abstract algebra extends the familiar concepts found in elementary algebra and arithmetic of numbers to more general concepts.

Here are listed fundamental concepts in abstract algebra. Rather than just considering the different types of numbersabstract algebra deals with the more general concept of sets: All collections of the familiar types of numbers are sets. Set theory is a branch of logic and not technically a branch of algebra.

The notion of binary operation is meaningless without the set on which the operation is defined. The numbers zero and one are abstracted to give the notion of an identity element for an operation. Zero is the identity element for addition and one is the identity element for multiplication.

Not all sets and operator combinations have an identity element; for example, the set of positive natural numbers 1, 2, 3, The negative numbers give rise to the concept of inverse elements. Addition of integers has a property called associativity.

That is, the grouping of the numbers to be added does not affect the sum. This property is shared by most binary operations, but not subtraction or division or octonion multiplication. Addition and multiplication of real numbers are both commutative.

That is, the order of the numbers does not affect the result. This property does not hold for all binary operations.

For example, matrix multiplication and quaternion multiplication are both non-commutative. Group theory and Examples of groups Combining the above concepts gives one of the most important structures in mathematics: Every element has an inverse: The operation is associative: For example, the set of integers under the operation of addition is a group.The key word "same" in this problem means that I am going to set my two expressions equal to each other.

When we set the two expressions equal, we now have an equation with variables on both sides.

After solving the equation, you find that x = 30, which means that after 30 weeks, you and your sister will have the same amount of money.
