Solve the Arithmetic Expression: 8+6-4 Step by Step

Q: Why can't I do 6 - 4 first since it's easier?

Great question! While you get the same answer here, order matters in math. Always follow left-to-right for addition and subtraction to build good habits for harder problems.

Q: What if I accidentally calculated 8 + 6 - 4 = 18?

You might have added all numbers together! Remember that subtraction means taking away. The expression is 8 + 6 - 4, not 8 + 6 + 4.

Q: Is there a faster way to solve this?

You could think of it as $ 8 + (6 - 4) = 8 + 2 = 10 $, but stick to left-to-right until you're very comfortable with order of operations!

Q: How do I check if 10 is really the right answer?

Try working backwards: 10 + 4 = 14, and 14 - 6 = 8. Since we get back to our starting number, 10 is correct!

Q: What if the numbers were bigger - would I still go left to right?

Absolutely! Whether it's $ 8 + 6 - 4 $ or $ 158 + 67 - 43 $, always work left to right for same-level operations.

Final Answer

Key Points to Remember

Essential concepts to master this topic

Order: Perform addition and subtraction from left to right
Technique: First calculate 8 + 6 = 14, then 14 - 4
Check: Verify by working backwards: 10 + 4 = 14, then 14 - 6 = 8 ✓

Common Mistakes

Avoid these frequent errors

Doing subtraction before addition
Don't calculate 6 - 4 = 2 first, then 8 + 2 = 10! This ignores the left-to-right rule and can give wrong answers in more complex problems. Always work from left to right when operations have equal priority.
