Solve the Expression: 2 + 0 ÷ 3 Step by Step

Q: Why do I divide first instead of going left to right?

The order of operations (PEMDAS) tells us that division and multiplication come before addition and subtraction, regardless of position. Always follow this rule!

Q: Is 0 ÷ 3 the same as 3 ÷ 0?

No! $ 0 ÷ 3 = 0 $ (zero divided by a number equals zero), but $ 3 ÷ 0 $ is undefined (you cannot divide by zero).

Q: How can I remember the order of operations?

Use the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). Some remember it as "Please Excuse My Dear Aunt Sally."

Q: What if there were parentheses in this problem?

Parentheses would change everything! If the problem were $ (2 + 0) ÷ 3 $, you'd calculate inside parentheses first: $ 2 ÷ 3 = 0.67 $.

Key Points to Remember

Essential concepts to master this topic

PEMDAS Rule: Division comes before addition in order of operations
Technique: Calculate $0 ÷ 3 = 0$ first, then add 2
Check: Final calculation $2 + 0 = 2$ gives correct answer ✓

Common Mistakes

Avoid these frequent errors

Adding first instead of following order of operations
Don't calculate 2 + 0 = 2, then divide by 3 = 0.67! This ignores PEMDAS and gives the wrong answer. Always do division before addition: calculate 0 ÷ 3 = 0 first, then 2 + 0 = 2.
