Ang MDAS ay di mawawala sya kahit anong Aptitude Test, katulad ng Civil Service Exam, at madalas naiipost sa FB.
Subukan nyo muna sagotan bago mag react. :)

7-4+12÷3×2 = ?
A. 10
B. 11
C. 5
D. 9
E. 6


Correct Answer is B. 11

Sa MDAS Rules uunahin muna ang Multiplication or Division, bago gawin ang Addition or Subtraction. So, paano nga ba naging 11 ang correct answer niya.

7-4+12÷3×2
Kompleto ang apat na operation sa equation, Ang order of operation ay pagsolve mula sa left to right. Kaya mauuna muna ang division bago ang multiplication.
7-4+4×2
Sa isang equation either multiplication or division ang mauuna depende kung alin ang nasa left.
7-4+8
Same as Addition and subtraction mauuna kung alin ang nasa left.
3+8

Answer is 11

Ang calculator po ay accurate yan pwede nyo po itry kung tama.
