To solve , you apply the operations from left to right, following the order of operations.
Start with the first two numbers and subtract:
Then take the result and subtract the next number:
Finally, add the last number:
Thus, the correct answer is .
12
Solve the following equation:
\( 12+7-5\text{ }= \)
Addition and subtraction have equal priority in order of operations, so you must work left to right. Changing the order changes the meaning of the expression and gives wrong answers.
If you calculated 4+8=12 first, then 11-3-12, you'd get -4 instead of 12! Always follow left-to-right order to avoid this mistake.
No! This follows PEMDAS perfectly. Since we only have addition and subtraction (same priority level), we work left to right as PEMDAS requires.
Think of it like reading a sentence - you read from left to right, word by word. Do the same with math operations of equal priority!
Parentheses always come first in PEMDAS! Calculate inside parentheses, then continue left to right for any remaining addition and subtraction.
