What will the value of the following expression be? $20 - [15 - \{4 - (8 - 6 + 3)\}]$
To solve the given expression \(20 - [15 - \{4 - (8 - 6 + 3)\}]\), we need to follow the order of operations, often abbreviated as BODMAS/BIDMAS (Brackets, Orders/Indices, Division and Multiplication, Addition and Subtraction).
- Start with the innermost bracket: \((8 - 6 + 3)\).
- Calculate \(8 - 6 = 2\).
- Then calculate \(2 + 3 = 5\).
- Replace the innermost bracket with the result: \(20 - [15 - \{4 - 5\}]\).
- Solve the next bracket \(4 - 5\):
- Calculate \(4 - 5 = -1\).
- Replace in the expression: \(20 - [15 - (-1)]\).
- Solve the bracket \(15 - (-1)\):
- Calculate \(15 + 1 = 16\) (since subtracting a negative is equivalent to adding).
- Replace in the expression: \(20 - 16\).
- Finally, calculate \(20 - 16 = 4\).
Thus, the value of the expression is 4, which corresponds to the correct answer option.
