• A. 1507
• B. 1437
• C. 1652
• D. 1577

Answer 1

Answer:

D. 1577

The value of the expression is 1577.

Following the BODMAS / PEMDAS rules, solve the expression from the innermost brackets outward:

• Step 1: Solve the round brackets ( )
  $100 - 60 - 7 = 33$
  The expression becomes: $1850 - [450 - \{210 - 33\}]$

• Step 2: Solve the curly braces { }
  $210 - 33 = 177$
  The expression becomes: $1850 - [450 - 177]$

• Step 3: Solve the square brackets [ ]
  $450 - 177 = 273$
  The expression becomes: $1850 - 273$

• Step 4: Perform the final subtraction
  $1850 - 273 = 1577$
