What is a number that expresses exponents?
An expression which combines numbers and operations
When you replace the variable with a number and perform the operations you blank an expression?
When you replace the variable with a number and perform the operations, you evaluate an expression. This process involves substituting the numerical value for the variable and simplifying the expression according to the given operations. Evaluation is a fundamental concept in mathematics and is used to determine the value of the expression under specific conditions.
What is the definition of algebraic expression-?
Here is the correct defenition: Algebraic Expression is an expression which is obtained by performing a finite number of the following operations on symbols representing numbers: addition, subtraction, multiplication, division, raising to a power.
Expression?
A number sentence that equals or that has an equal sign.
Is the number sentence 8 plus 2 equals 10 an expression or an equation?
That word "equals" in there makes it an equation.
What does the value of an expression mean?
If you replace variables in an expression by numbers (in case there are any variables) and then do the indicated operations, you get a number. That final number is the "value" of the expression.
What is an algebraic expresion?
an algebraic expression is an expression built up from constants, variables, and a finite number of algebraic operations (addition, subtraction, multiplication,division and exponentiation to a power that is a rational number). For example,
What is an algebraic expression by replacing each variable with a given number and performing all operations?
It is called evaluating the equation.
What is the relationship between an expression and an equation?
An equation states that an expression is equal to either a number or another expression.The 'equals' sign ( = ) is the tip-off that you have an equation.
Is a expression the number multiplied to a variable?
An expression can be that, but it can also be a combination of such terms and other mathematical operations. For example, 3a + 27b^2/sin(27c) provided c is not 0.
What is the variable expression for two more than three times a number?
3x+2. x equals any given number.
In mathematics what is the meaning of operations?
A mathematical operation is a process such as addition, subtraction, multiplication or division. The word can also include the use of brackets or parentheses, squaring a number, integrating, differentiating, and so on. Basically, this covers any process that changes the value or state of the number or expression on which it is operating.
