....One of the easiest ways to mess up an algebra problem is to solve things in the wrong order. Become very familiar with the order of operations, and make sure you always solve in the correct order. One way to help you remember the order of operations is to think of the sentence: "Please excuse my dear Aunt Sally." PEMDAS is the order of operations: parentheses, exponents, multiplication, division, addition and subtraction. Move from left to right when solving within a step.

so that's the rule. do not change the rule.

the phrase "move from left to right" simply instructs to look for the right order of operation which follows the rule of PEMDAS.
sir mukhang mali ata pagkakaintindi mo sa PEMDAS, ganito yan:

If the expression consists of parenthesis, exponents, +, –, × and ÷, then the operations MUST be performed in the following order.

Always work on the calculations within parenthesis first if any.
Next, calculate the exponents.
Then, carry out multiplication OR division, working from left to right.
Lastly, do addition OR subtraction, working from left to right.

marami ang hindi nakakapansin ng salitang OR dun sa rule ng PEMDAS, hindi po in order yung multiplication and division, pantay lang po ang priority nila, so kung ganun ang case dapat from left to right mo isolve ang problem.
