Given expression: 43 C 29 B 3 A 14 B (5 C 4) C 11 C (14 A 3) A 64 D 8 B 2 According to the question; A is -; B is x; C is +; D is / So by substituting these expressions in the given expression the expression becomes; 43 + 29 x 3 - 14 x (5 + 4) + 11 + (14 - 3) - 64 / 8 x 2. Now follow the BODMAS rule. = 43 + 29 x 3 - 14 x 9 + 11 + 11 - 8 x 2 = 43 + 87 - 126 + 11 + 11 - 16 = 130 - 126 + 22 - 16 = 130 - 104 - 16 = 26 - 16 = 10 |
