PEMDAS - Parenthesis , Equation , Multiplication, Division, Addition, Substraction
Multiplication and Division - kung sino mauuna sa kanila (Left to right lang lagi don't forget)
Addition and Substraction - pwedeng magbaliktad
let me give you some example:
24 + 6 / 3 * 5 * 2^3 - 9 (exponent first since wala naman parenthesis)
24 + 6 / 3 * 5 * 8 - 9
Now, tingnan mo yung multiplication (M) and division (D) from left to right, ignore mo muna yung addition and substraction . (yung iba uunahin isolve yung multiplication since nauuna ang multiply sa PEMDAS pero base sa rules ng multiplication and division laging magsisimula sa left to right sa example sa baba mauuna ang division)
Correct way:
24 + 6 / 3 * 5 * 8 - 9 =
24 + 2 * 5 * 8 - 9 =
24 + 10 * 8 - 924 + 80 - 9
Lastly, I complete addition (A) and subtraction (S) from left to right.
24 + 80 - 9 =? =
104 - 9 = 95
Wrong way:.
24 + 6 / 3 * 5 * 8 - 9 (yung iba uunahin multiply kesa divide PEMDAS nga daw kasi)
24 + 6 / 15 * 8 - 9
24 + 6 / 120 - 9
24 + 0.05 - 9 =
24.05 - 9 = 15.05 (as you can see magkaiba sila ng sagot)
