### How can you solve problems involving equivalent expressions?

In the same way that you would solve equations because equivalent expressions are in effect equations

yes

### How do you solve an algeraba problem?

There are lots of different types of problems in algebra; you have to learn each type separately. For example, how to add similar expressions; how to multiply expressions; how to factor polynomials; how to solve equations; etc.

### How are word problems with equations different from word problems with expressions?

It may be possible to solve equations. Expressions cannot be solved until they are converted, with additional information, into equations or inequalities which may have solutions.

### How are number patterns expressions and equations used to solve problems?

the sum of a number and 16 is equal tu 45

### What are differences between numerical methods and numerical analysis?

A numerical method is the same as an algorithm, the steps required to solve a numerical problem. Algorithms became very important as computers were increasingly used to solve problems. It was no longer necessary to solve complex mathematical problems with a single closed form equation. See link on algorithm. According to Wikipedia: Numerical analysis is the study of algorithms for the problems of continuous mathematics (as distinguished from discrete mathematics). See link on numerical analysis. An expanded definition offered by K.E. Atkinson is: Numerical analysis is the area of mathematics and computer science that creates, analyzes, and implements algorithms for solving numerically the problems of continuous mathematics. Such problems originate generally from real-world applications of algebra, geometry and calculus, and they involve variables which vary continuously; these problems occur throughout the natural sciences,Social Sciences, engineering, medicine, and business. Numerical analysis courses typically are offered as part of Industrial engineering (Operations research), applied mathematics, computer science. Simulation, operations research and computer science are very interrelated

### How do you solve algebraic expresions?

You solve algebraic expressions by getting the variable by itself.

### How do you solve algabraic expressions?

Expressions are just expressions. Art is an expression and no one can "solve" art. You need problems to solve. In algebra, you'll most likely be looking for equations to solve. Generally you are looking for a simple way to express a variable or to equate the variable to a number. This can be done using what are called "algebraic manipulations". Usually this involves just adding, subtracting, multiplying or dividing each side of an equation (an expression need not have "sides"), however there are many, many different operations than these. wow does that suck....the answer is Elmo

### When evaluating a numerical expression you should simplify all expressions inside what first?

Think of the saying,"Please Excuse My Dear Aunt Sally." You solve inside the parentheses first, then exponents, multlipication/division, and finally addition/subtraction.
