To find the value of a numerical or algebraic expression, you need to substitute the given values or variables into the expression and then simplify it to get the final result.
For example, if the expression is 3x + 2 and x = 5, to find the value of the expression, substitute x = 5 into the expression:
3(5) + 2 = 15 + 2 = 17
So, the value of the expression 3x + 2 when x = 5 is 17.
Coefficient refers to the numerical or constant factor that is multiplied by a variable term in an algebraic expression or equation. For example, in the expression 3x, the coefficient is 3, and in the equation 2y + 7 = 0, the coefficient of y is 2.
To subtract means to find the difference between two numbers or expressions by taking away one quantity from another. For example, subtracting 5 from 10 means to take 5 away from 10, resulting in the difference of 5.

To find the value of a numerical or algebraic expression, you can:
1. Evaluate: Substitute the given values or variables into the expression and simplify it to find the final result. This involves performing any necessary mathematical operations such as addition, subtraction, multiplication, or division.
2. Coefficient: Identify and understand the coefficient, which is the numerical or constant factor that is multiplied by a variable term in an algebraic expression or equation. The coefficient is a number that tells you how many times the variable is multiplied.
3. Subtract: Determine the difference between two numbers or expressions by taking away one quantity from another. This involves performing the operation of subtraction, where you subtract one value from another to find their difference.
