Explanation:

From the given conditions we understand that the following operators are to be replaced by corresponding operators to get required answer.
‘–’ → ‘×’
‘÷’ → ‘+’
‘×’ → ‘–’
‘+’ → ‘÷’
The given equation is: 100 – 10 × 1000 ÷ 1000 + 100 × 10
Thus after changing the operators we form the equation as:
100 × 10 – 1000 + 1000 ÷ 100 – 10
Solving by BODMAS, we get,
1000 – 1000 + 10 – 10 = 0
