Step-by-Step Analysis
Interchange Operators:
The original expression is: 4515 × 5 - 431 ÷ 3 + 821
Instructions: Interchange + with - and × with ÷.
New expression: 4515 ÷ 5 + 431 × 3 - 821
Calculate according to BODMAS:
Division: 4515 ÷ 5 = 903
Multiplication: 431 × 3 = 1293
Expression now: 903 + 1293 - 821
Addition: 903 + 1293 = 2196
Subtraction: 2196 - 821 = 1375
