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 arithmetic! Addition and subtraction have the same priority level, so you must work left to right. Changing the order can give you a different (wrong) answer.
That's okay! Just start over and be extra careful to work from left to right. Use your finger to track which operation you're doing next.
Try grouping the numbers differently but still following left-to-right order. For example: . You should get the same answer!
You can look for patterns like combining opposites, but always verify by doing it the standard left-to-right way. Mental math shortcuts are great, but accuracy comes first!
Always solve what's inside parentheses first, then continue left to right with the remaining operations. Parentheses change the order of operations!
