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!!!!!
