(3*5)+(6 to the power of 2)+54-5
It is called "to evaluate" the expression.
Any "expression" that represents a numeric value. Example: 2+2=4 or x+7=10. Actually the examples above are equations, not expressions. Expressions do not have = signs. 7a and 4x are examples.
Is the value obtained when all the variables have been given their value and the expression has been calculated according to mathematical rules.
An expression using a variable could be ( 3x + 5 ), where ( x ) represents a number. In this expression, ( 3x ) indicates three times the value of ( x ), and ( 5 ) is a constant added to it. This type of expression can be used in various mathematical contexts, such as solving equations or modeling real-world situations.
It would help if the expression was given!

A mathematical expression is a mathematical phrase that consist numbers variables and signs of operation example: x(variable) + 5(number)=7 so the value of x is 2 -Kennethn 10 yrs. old :]

"N added to 3" refers to the mathematical expression 3 + N, where N represents a variable or a number. The result will depend on the value of N; for example, if N is 2, then the expression equals 5. If N is not specified, the expression remains as 3 + N.
Depends what the expression is. Just plug in 8 for y in the expression and that'll do it for you.
square root of 0.2^-2=5
Yes.
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
The value of a keyword as a real number is its numerical representation in the context of a mathematical expression or equation.
It is a combination of numbers and variables, linked together by mathematical functions. For example sqrt(2y/3*7.34*pi) where y is some variable. Given the value(s) of the variable(s) it is possible to evaluate (find the value of) the expression.
