In algebra, an expression is a combination of numbers, variables, and mathematical operators (such as addition, subtraction, multiplication, and division) that represents a value. Unlike an equation, an expression does not include an equality sign and cannot be solved for a specific value. For example, (3x + 5) is an algebraic expression where (x) is a variable. Expressions can be simplified or evaluated by substituting values for the variables.
An expression in mathematics is a combination of numbers, variables, and operators (such as addition, subtraction, multiplication, and division) that represents a value. Unlike an equation, it does not include an equality sign. Expressions can be simplified or evaluated to yield a numerical result. For example, (3x + 5) is an expression where (x) is a variable.
In the absence of parentheses, multiplication and division are carried out before addition and subtraction. In this case, add 5 to whatever is happening with the five and the two.
In general, the answer to a subtraction problem is not a product; it is a difference. Subtraction involves taking one number away from another, resulting in a value that represents how much remains. A product, on the other hand, is the result of multiplication. Therefore, while subtraction and multiplication are both mathematical operations, their results are fundamentally different.
Evaluating a numerical expression means calculating its value by performing the operations indicated in the expression, such as addition, subtraction, multiplication, and division. This process often involves following the order of operations (PEMDAS/BODMAS) to ensure that calculations are performed correctly. The result is a single numerical value that represents the expression. For example, evaluating the expression (3 + 5 \times 2) would yield (13).

To calculate the value of an expression or equation involves determining its numerical result by performing the necessary mathematical operations, such as addition, subtraction, multiplication, or division. This process often follows the order of operations (PEMDAS/BODMAS) to ensure accuracy. For example, in the expression (3 + 5 \times 2), you would first multiply 5 by 2 and then add 3, resulting in a final value of 13.
To find the value of an expression in lowest terms, first simplify the expression by performing any necessary operations, such as addition, subtraction, multiplication, or division. If the expression is a fraction, factor both the numerator and the denominator to identify and cancel any common factors. Finally, ensure that the resulting fraction is in simplest form by confirming that the numerator and denominator have no common factors other than 1.
A numerical expression in math is a combination of numbers and mathematical operations (such as addition, subtraction, multiplication, and division) without any variables. It represents a specific value when the operations are carried out. For example, the expression (3 + 5 \times 2) is a numerical expression that evaluates to 13. Numerical expressions are used to perform calculations and solve mathematical problems.
To evaluate a variable expression, first substitute the values of the variables with their corresponding numerical values. Next, perform the arithmetic operations in the correct order, following the rules of parentheses, exponents, multiplication and division, and addition and subtraction (PEMDAS/BODMAS). Finally, simplify the expression to obtain the final value.
A calculation that involves one or more mathematical operators is called an expression. An expression can include numbers, variables, and operators such as addition, subtraction, multiplication, and division. It represents a value that can be evaluated or simplified.
mathematical order of operations stands for: Parentheses Exponents Radicals Absolute Value Multiplication Division Addition Subtraction
Both an equation and an expression are mathematical constructs used to represent relationships between numbers or variables. They both involve mathematical operations such as addition, subtraction, multiplication, and division. However, while an expression represents a value and does not contain an equality sign, an equation states that two expressions are equal by including an equality sign.
When a math problem instructs you to "evaluate each expression," it means you need to compute the value of the given mathematical expressions using the specified numbers or variables. This involves performing the necessary arithmetic operations, such as addition, subtraction, multiplication, or division, to arrive at a numerical result. Essentially, you're simplifying the expression to find its value based on the provided inputs.
