When evaluating an expression, do these in this order:
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.
To evaluate an expression means to find its numerical value. A power consists of a base and an exponent. According to the order of operations, operations inside parentheses (or other grouping symbols) are performed first, followed by the evaluation of powers ... then (*/) and (+-).
This is called algebra. In algebra you can have many operations. You can add, subtract, multiply, divide, square, cube, square root, factor, or distribute. There are others but these are the main ones. You use these operations to find the numerical value of the variable.
In the context of algebra, "4d" would typically be considered a numerical expression rather than a variable. A variable is typically a letter or symbol that represents an unknown quantity that can vary, while a numerical expression is a combination of numbers and mathematical operations. In this case, "4d" represents the product of the number 4 and the variable "d," making it a numerical expression.

Numerical Expression
A numerical expression.
An expression consisting of numbers and operations.
Simplifying an expression is getting rid of any brackets or parentheses, performing as many operations as you can - including combining like terms. To evaluate an expression you would substitute the numerical values of all the variables, carry out all the operations (addition, multiplication etc) in the expression to reach the answer - the numerical value of the expression.
Yes.
