Question

Tính :

a , /49/ - / -12/

b, (-25) +35

c,(-12)-(-8)

d,(-192)-(97-192)

Answer 1

a, \(\left|49\right|-\left|-12\right|\)

\(=49-12\)

\(=37\)

b, \(\left(-25\right)+35=10\)

c, \(\left(-12\right)-\left(-8\right)=-4\)

d, \(\left(-192\right)-\left(97-192\right)\)

\(=-192-97+192\)

\(=-192+192-97\)

\(=0-97\)

\(=-97\)

Answer 2

a, = 49 -12 =37

b, = 35-25=10

c,=-12+8=-4

d.= -192-(-95)=-192+95=-97

Answer 3

A /49/-/-12/=

= 49 - 12 =37

B (-25) + 35 = 10

C (-12) - (-8) =

= -12 + -8 = -20

D (-192) - ( 97-192) =

= ( -192+192 ) - 97

= 0 - 97

= -97

=

Answer 4

a) \(\left|49\right|-\left|-12\right|=49-12=37\)

b) \(\left(-25\right)+35=35-25=10\)

c) \(\left(-12\right)-\left(-8\right)=-12+8=-4\)

d) \(\left(-192\right)-\left(97-192\right)=-192-97+192\)

\(=-97\)
