SIMPLIFY (USING BODMASS)
Answers
All the solutions shown below are done according to the BODMAS Rule.
(i) 27-[5+{28-(29-7)}]
= 27 - [5 + {28 - (22)}]
= 27 - [5 + {28 - 22}]
= 27 - [5 + {6}]
= 27 - [5 + 6]
= 27 - [11]
= 27 - 11
= 16
______________
(ii) 39-[23-{-(17-9+3)}]
= 39 - [23 - {- (17 - 6)}]
= 39 - [23 - {-(11)}]
= 39 - [23 - {-11}]
= 39 - [23 + 11]
= 39 - 34
= 5
_____________
(iii) -25+14÷(5-3)
= - 25 + 14÷(2)
= -25 + 7
= -18
_______________
(iv) 45-[38-{60÷3-(6-9÷3)÷3}]
= 45 - [38 - {20 - (6 - 3) ÷ 3}]
= 45 - [38 - {20 -3/3}]
= 45 - [38 - {20 - 1}]
= 45 - [38 - 19]
= 45 - [19]
= 45 - 19
= 26
________________
(v) 118-[121÷(11x11)-(-4)-{3-9+2}]
= 118 - [121 ÷ (121) + 4 + {-6 + 2}]
= 118 - [1 + 4 + {-4}]
= 118 - [1 + 4 - 4]
= 118 - [1]
= 118 - 1
= 117
_______________
Hope it helps.
