Solve the Expression: Evaluating 10-3+7-5 Step by Step

Addition and subtraction have equal priority in order of operations! When operations have the same priority, you must work left to right. Doing additions first would change the meaning of the expression.

You likely calculated $10-(3+7-5)$ instead of working left to right. Remember: no parentheses means no grouping - just go step by step from left to right!

Try thinking of it as a number line: start at 10, move left 3 spaces (to 7), move right 7 spaces (to 14), then move left 5 spaces (to 9). Or verify each step: $10-3=7$, $7+7=14$, $14-5=9$.

Yes! You can combine like operations: $10+7=17$ and $3+5=8$, then $17-8=9$. But be careful - this only works when you keep track of positive and negative signs correctly.

This problem only uses addition and subtraction, which are at the same level in PEMDAS. When operations have equal priority, you work left to right - no other PEMDAS rules needed here!
