Solve Sequential Division: 10 ÷ 2 ÷ 1 Step-by-Step

Q: Why do I work from left to right with division?

Division has the same priority level as multiplication, so when you have multiple divisions in a row, you must work left to right. This is a fundamental rule of order of operations!

Q: What if I accidentally calculated 2 ÷ 1 first?

If you calculated $ 2 \div 1 = 2 $ first, then $ 10 \div 2 = 5 $, you'd get the wrong answer! Always start with the leftmost operation in sequential division.

Q: Does dividing by 1 change the number?

No! Dividing any number by 1 gives you the same number. So $ 5 \div 1 = 5 $. This is why our final answer is 5.

Q: How can I remember the correct order?

Think of it like reading a book - you read from left to right! When operations have equal priority (like division and division), always work left to right.

Q: What if there were parentheses in this problem?

Parentheses would change everything! You'd solve what's inside the parentheses first, then work left to right with the remaining operations.

Final Answer

Key Points to Remember

Essential concepts to master this topic

Order Rule: Division operations are performed strictly from left to right
Technique: First calculate $10 \div 2 = 5$ , then $5 \div 1 = 5$
Check: Working left to right gives 5, not 2 ✓

Common Mistakes

Avoid these frequent errors

Calculating division operations in wrong order
Don't calculate $2 \div 1 = 2$ first, then $10 \div 2 = 5$ ! This ignores the left-to-right rule and gives the wrong answer of 2. Always work from left to right with equal operations.
