What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The order is: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Often remembered by the acronym PEMDAS.

What does 'Parentheses' mean in Order of Operations?

Back

Parentheses are symbols used to group parts of a mathematical expression. Calculations inside parentheses are performed first.

Front

What does 'Exponents' mean in Order of Operations?

Back

Front

What is the first operation to perform in the expression 10 - 4 ÷ 1 x 5?

Back

The first operation to perform is Division.

Front

What is the result of the expression 18 + (6 – 2) × 2?

Back

The result is 26.

Front

What is the error in the calculation 5 - 3 + 2 = 0?

Back

The error is that addition was done first instead of subtraction. The correct order is to subtract first.

What is the correct order of operations for the expression 50 - 16 x 2 ÷ (12 - 4)?

Back

The correct order is: Parentheses, Multiplication, Division, Subtraction.

How do you insert parentheses to make 3 + 5 × 2 - 10 = 6 true?

Back

Front

What is Multiplication in the context of Order of Operations?

Back

Multiplication is one of the basic arithmetic operations, where a number is added to itself a certain number of times. In the order of operations, it is performed after parentheses and exponents.

Front

What is Division in the context of Order of Operations?

Back

Division is the process of determining how many times one number is contained within another. In the order of operations, it is performed after parentheses and exponents, and before addition and subtraction.
