what is the difference between simplifying an expression and evaluating an expression?
7966
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same. To represent equivalent expressions an equality = sign is used. 3x+2 and 3x + 6 are equivalent expressions, because the value of both the expressions remains same for any value of x.

The main difference between a function expression and a function declaration is the function name, which can be omitted in function expressions to create anonymous functions. A function expression can be used as an IIFE (Immediately Invoked Function Expression) which runs as soon as it is defined.

Equivalent algebraic expressions are those expressions which on simplification give the same resulting expression. Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same. To represent equivalent expressions an equality = sign is used.

Algebraic expressions are useful because they represent the value of an expression for all of the values a variable can take on. 5 + 2 5+2 5+2 . Similarly, when we describe an expression in words that includes a variable, we're describing an algebraic expression, an expression with a variable.

An equation is two expressions that are equal to each other. Short Answer: an expression can include numbers, variables, operators, sets, matrices, and other single things that can all be evaluated to one thing. An equation is two expressions that are equal to each other.

Expressions are easy to plot, differentiate (with diff), or integrate, and the result is always another expression, which can be further manipulated. Functions, on the other hand, are a little harder to define and the result of applying a Maple command to a function is not always a function.

An algebraic expression is a combination of integer constants, variables, exponents and algebraic operations such as addition, subtraction, multiplication and division. 5x, x + y, x-3 and more are examples of algebraic expression. ... A variable is a letter used to represent an unknown value.

The only difference is that (a) the body of a lambda can consist of only a single expression, the result of which is returned from the function created and (b) a lambda expression is an expression which evaluates to a function object, while a def statement has no value, and creates a function object and binds it to a ...

An expression is considered simplified only if there is no radical sign in the denominator. If we do have a radical sign, we have to rationalize the denominator . This is achieved by multiplying both the numerator and denominator by the radical in the denominator.

I assume you're asking about the difference in meaning rather than in the way these are written down, so here's my take on this. In my opinion, the only difference here is that inequality is a condition on the values involved, while the interval notation is more of a description.
