According to the order of operations, we solve the exercise from left to right:
7
\( 94+12+6= \)
Great question! When operations have equal priority (like addition and subtraction), you must work left to right. Changing the order can give you a different answer, which would be incorrect.
You probably calculated 4+5+1-3 as 4+(5+1-3) = 4+3 = 7. Remember to work strictly left to right: first 4+5=9, then 9+1=10, finally 10-3=7.
Yes! You can group all positive numbers and all negative numbers: (4+5+1) + (-3) = 10-3 = 7. But make sure you understand the left-to-right rule first!
For addition and subtraction only, it's simple: always go left to right. Think of it like reading - you wouldn't skip around words in a sentence!
The same rule applies! Whether it's 4+5+1-3 or 24+15+11-13, you still work left to right. The size of numbers doesn't change the order of operations.
