Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:
\( 0:7+1= \)
Because order matters in mathematics! The expression must be solved from left to right. Rearranging changes the meaning and gives wrong answers.
That's why we work one operation at a time! Write down each intermediate result: 32-4=28, then 28-19=9, then 9+3=12, finally 12-7=5. This prevents errors and makes checking easier.
Think of it like reading a sentence - you read from left to right! When addition and subtraction are mixed together, treat them with equal importance and solve in the order they appear.
Go back and check each step carefully. The most common error is working out of order. Make sure you calculated: , , ,
Yes! This follows the MD and AS rules from PEMDAS. Since we only have addition and subtraction (no parentheses, exponents, or multiplication/division), we work left to right as these operations have equal priority.
