12*2=???
ai k mk mk k lai
12-12=
Ai k mk , mk k lai
12 - 12
= 12 . 1 - 12 .1
= 12 . ( 1- 1 )
= 12 . 0
= 0
13-12=
Ai k mk mk k lai
13 - 12 = 1 nhé Sakura kinomoto
Tk mik , mik tk lại
\(x+12-45=78\)
kb với mk nha
ai k mk mk mk k lai
x + 12 - 45 = 78
x + 12 = 78 + 45
x + 12 = 123
x = 123 - 12
x = 111
Vậy x = 111
x+12-45=78
x+12 =78+45
x+12 = 123
x =123-12
x 111
22*2=???
ai k mk mk k lai
62+2=??
ai k mk mk k lai
1+1000000000000000000000000
ai k mk mk k lai
ai nhanh mk k
1 + 1000000000000000000000000000 =1000....00001
1+1000000000000000000000000=1000000000000000000000001
(-2)+(-102)=
120+(-10)=
ai k mk mk k lai
(-2)+(-102)
=-(2+102)
=-104
120+(-10)
=+(120-10)
=+110
k nhé rùi mk k lại cho
( -2) + (-102) = -104
120 + (-10) = 110
k đi
k lại
1+10=?
nhanh mk k ai k mk mk k lai
190 - 35 =...
Ai k mk , mk k lai
190 - 35
= 155
