Workshop fo seventh
Solve the following operation and check if the answer are true( do the process)
a) (12 – 2 ) : ( 1 – 6 ) = – 2
b)) – 2 + (– 5 – 12 : 3 ) . (– 3 + 4 : 2
) = 7
c) – 11 + (– 4 + 7
– 11 ) . (– 3 + 6 ) = – 35
d) – 11 – (– 2 + 8 . 4 ) : ( 7 – 4 . 7 + 6
) = –
9
e) – 2 – (– 5 – 7 )
: (– 4 + 5 – 3 ) = – 8
f) – (– 2 . 4 + 12 : 3 ) : ( 11 – 3 . 2 – 1 )
= 1
g)
(– 3 + 5 – 2 ) . (– 8 + 3 ) – (– 5
) . (– 3 + 7 ) = 20
h)
– (– 3 + 3 . 5 ) : (– 2 . 2 ) + (– 2 ) . (– 1
+ 14 : 2 ) = – 9
Solve the following iperation have inmind( divisions are firsta than additiona and subtraction)
a) 5 – 12 : 3 +
7 =
8
b) (– 3 ) – (- 24 ) : (- 2 ) + 5
– 8 : 4 = – 12
C) 6 + 8 + 15 : (–
3 ) + 4 = 13
d) – (– 30 ) : 6 + 5 + 24
: (– 3 ) = 2
e) 4 – 21 : (– 3 )
+ 12 : (– 3 ) = 7
f) 4 + 7 –
18 : (– 6 ) + 42 : 7 – 8 = 12
g) (– 8 ) : 2 – (–
4 ) – (– 3 + 2 ) = 1
h)
2 + 6 : (– 3 ) – 24 : (– 6) + (– 72) : 12 = –2
The two points : represent divisions!!!!!
