Answer»

FOLLOW BODMAS rule to solve this question, as per the ORDER given below,

Step-1: Parts of an equation enclosed in ‘BRACKETS’ must be solved first.

Step-2: Any mathematical ‘Of’ or ‘EXPONENT’ must be solved next.

Step-3: Next, the parts of the equation that contain ‘Divison’ and ‘Multiplication’ are calculated.

Step-4: LAST but not the least, the parts of the equation that contain ‘Addition’ and ‘Subtraction’ should be calculated.

Given expression:

16.75 - [2.25 + {1.28 + (7.43 - (6.02 - 0.23))}]

= 16.75 - [2.25 + {1.28 + (7.43 - 5.79)}]

= 16.75 - [2.25 + {1.28 + 1.64}]

= 16.75 - [2.25 + 2.92]

= 16.75 - 5.17

= 11.58
