If a*b=(a+1) x b, compute 3*(4*5) =.....................
If a x b=(a+1) x b . We will have :
3 x (4 x 5) = 3 x(4+1) x5 =3 x 5 x 5=75
Inferred 3 x (4 x 5)=75
(-25) +(-58)-(-21)
tính nhanh
(-39)+67+(-19)+(-67)
b) 246-(357-246)
c)-111-(987-111)
d) (1234-4567)-(1234-67)
e) (134-388)-(12+134)
tìm y
y x 3= 246-12
y x 3 = 246 – 12
y x 3 = 234
y = 234 : 3
y = 78
y x 3 = 246 - 12
y x 3 = 234
y = 234 : 2
=> y = 117
Bài 4 tìm y
Yx3=246-12
Y:3+5=215
yx3=246-12
yx3=234
y=234:3
y=78
y:3+5=215
y:3=215-5
y:3=210
y=210x3
y=630
y x 3= 246 - 12
3y= 246 -12
3y= 234 = 78
y= 78
+) \(Y\times3=246-12\)
\(Y\times3=234\)
\(Y=78\)
+) \(Y:3+5=215\)
\(Y:3=210\)
\(Y=630\)
