Simplification questions for class 6

For simplifying an expression , the order of performing the various operations should be strictly in  the following order :

(i) Brackets               (ii) of        (iii) Division           (iv) Multiplication      (v) Addition        (vi) Subtraction

Remember the wordBODMAS ‘  , where the letters  B, O, D, M,  A,  S stand for Brackets , of,  Division,  Multiplication,  Addition  and  Subtraction  respectively. 

Simplification questions for class 6 with answers: 

(i) Simplify :      12-[20÷{8-2(9-5-2)}]

Sol.    12-[20÷{8-2(9-5-2)}]=  12-[20÷{8-2 x 2}]      (removing small brackets)

=12-[20÷{8-4}]

=12-[20÷4]                  (removing braces)

= 12-5                              (removing big brackets)

=7

(ii)  4+4+4+4÷4

4+4+4+4÷4 =4+4+4+1                 (solving division)

=13

(iii)    25− [4 + {16 − (12 − 2)}]

25− [4 + {16 − (12 − 2)}] =  25− [4 + {16 − 10}]                                    (removing small brackets)

= 25− [4 + 6]                                                 (removing curly braces)

=25-10                                                          (removing big brackets)

=15

(iv)  36 − [18 − {14 − (15 − 4 ÷2 ×2)}] 

36 − [18 − {14 − (15 − 4 ÷2 ×2)}]= 36 − [18 − {14 − (15 − 2 ×2)}]                (Performing division  in small brackets)

=36 − [18 − {14 − (15 − 4)}]                       (performing multiplication)

= 36 − [18 − {14 − 11}]                       (removing small brackets)

=36- [18-3]                                              (removing curly braces)

=36-15                                                       (removing big brackets)

=21

(v)  10×10+[400÷{100-(50-\overline{3\times 10}

)}]

10×10+[400÷{100-(50-\overline{3\times 10})}] =10×10+[400÷{100-(50-30)}]          (removing bar)

=10×10+[400÷{100-20}]                   (removing small brackets)

=10×10+[400÷80]                             (removing braces)

=10×10+5                                             (removing big brackets)

= 100+5                                                 (performing multiplication)

= 105

(vi) 20[4+{16(12 3)}]

Sol.  20 – [4 + {16 – (12 – 3)}] = 20 – [4 + {16 – 9}]                        (Removing  small brackets)

= 20 – [4 + 7]                                    (Removing curly  brackets)

= 20 – 11                                           (Removing square brackets)

= 9

(vii ) 13-[20 ÷{8-2(9-5-2)}]

Sol. 13-[20 ÷{8-2(9-5-2)}]= 13-[20 ÷{8-2 x 2}]                 (removing small brackets)

=13-[20 ÷{8-4}]

=13-[20 ÷4]                                  (removing braces)

= 13-5                                             (removing big brackets)

=8

(viii) [30 ÷ {10- (8- simplification questions)}]

Sol. [30 ÷ {10- (8- \overline{6-2})}] = [30 ÷ {10- (8- 4)}]                  (removing bar)

=[30 ÷ {10- 4}]                           (removing small brackets)

=[30 ÷ 6]                                      (removing braces)

=5                                                   (removing big brackets)S
