To ensure accuracy in the calculation of mathematical operations, it is essential to follow a set of specific rules. These regulations establish the order of operations, facilitating the systematic and orderly resolution of mathematical expressions involving two or more operations. This approach allows breaking down the process step by step, ensuring proper and precise execution.
We present to you an excellent calculator for order of operations that will help you understand how to solve mathematical operations following the proper order of operations. This tool provides step-by-step solutions and the opportunity to visualize the process in a tree-like structure, revealing the order in which various operations have been resolved.
The order of operations calculator, also known as PEMDAS Calculator, automatically solves the expression as you input it. The syntax required for entering different operations is detailed in the following table, ensuring precise and efficient use of the tool.

The order of operations refers to a set of standardized rules that dictate the sequence in which various operations, such as addition, subtraction, multiplication, and division, should be performed.
Adhering to the proper order of operations is crucial for simplifying and solving various algebraic problems. Failure to apply the correct order of operations may lead to different interpretations of a mathematical expression among different individuals, resulting in divergent solutions. Consequently, precise adherence to these rules becomes critical to ensure consistency and accuracy in mathematical calculations.
PEMDAS is an acronym that represents the order of operations in arithmetic and algebraic expressions. Each letter stands for a specific operation to be performed in a given order:
Following the PEMDAS order ensures a consistent and unambiguous way to evaluate mathematical expressions and equations.
Below, we provide some examples of solving mathematical operations by applying the appropriate order of operations:
Example 01: Order of operations with exponents
In this example, we see how operations inside the parentheses are solved first, starting with the division of 9 by 3, and then proceeding with the addition operation. Subsequently, the result of the addition is squared. With the assistance of our calculator, we can better visualize the order of operations followed.
Example 02: Order of operations with fractions
