Sir malinaw po yung order of operations lalo na sa flow ng pagka discuss nyo. Nagtataka lang po ako sa isang teaching guide na nabasa ko kase eto yung nakalagay.

10 + 6 – 5 = n

In solving this kind of problem with two or more operations are involved, addition shall be done first and followed by subtraction.

10 + 6 – 5 =

16 – 5 =

Then, subtraction follows next.

16 – 5 = 11

The final answer is equal to 11.

Present additional illustrative example.

25 – 10 + 12 = ________

Solutions:

25 – 10 + 12 – 22 = 3

Bakit sa second example nya nauna pa din ang addition before sya nagsubtract. Wala naman pong parenthesis.
