mali man to, applying MDAS law,

4x4+4x4+4-4x4=
((4x4)+(4x4)+4)-(4x4)=
((16+16)+4)-(16)=
(32+4)-16=
36-16=
20
yan ang sag0t, 20

ang dali naman yan, grade skul lesson

trigo naman daw po para challenging..haha

trigo naman daw po para challenging..haha

50 + 50 = 100
(50 - 1) + (50 - 1) = 98
tama pa ung computation hanngang d2..

mali ung operation nung iniadd ung 1 a 98...
dapat ksi minus.. para mag equal sa 97 na price ng damit..
kapag kasi add 98 na utang mu + 1piso na sukli?? haha XD
diba dapat 98 na utang minus 1 na sukli???

36 po sagot ko..,,, =)
tama po ba??

#Problem 1
you saw a shirt for $ 97. U didn't have the money to buy it so u borrowed 50 from your mom and 50 from your dad = 100 . You bout the shirt and had $3 change . You gave your mon $1 and your dad $1 and kept a dollar for your self now you owe them each $49 . $49 +49 = 98 + your $1 = $99 . Where's the missing $1

Answer:
yung 1dollar ay nakay YOU! WAla namang kinalaman yun sa 2dollars na binalik ni YOU kay Mom and Dad, kaya talagang may utang padin si YOU kay Mom at Dad ng tig49dollars, kung iaaccount mo iyon.
#mga pera nyo
50-Mom 50-Dad 0-You 0-Bilihan
#nagkautangan na
0-Mom 0-Dad 100-You 0-Bilihan

#bumili na
0-Mom 0-Dad 3-You 97-Bilihan

#nagkasuklian na
1-Mom 1-Dad 1-You 97-Bilihan *(May utang ka padin na tig49dollars sa kanila)

#nagkabayaran na ng utang
50-Mom 50-Dad (-97)-You 97-Bilihan *(kung babayaran mo sila ng tig49, edi maglalabas ka ng pera na 98dollars? e di ba may
1dollar ka, kaya 49+49=98(bayarin mo sa kanila)-1(sukli sayo)=97(price ng damit)



#Problem 2
(4x4) + (4x4) + 4 - (4x4) = ?

Answer:
(4x4) + (4x4) - (4x4) + 4= ? (commutative property)
(4x4) + (4x4) - (4x4) + 4= ? [(same value) negative + positive = 0]
(4x4) + 0 + 4= ? (substitution)
(16) + 0 + 4 = 20 (answer)


Tama ba boss? Hehehe
