Question
In an imaginary mathematical system, symbol '–' stands for addition, symbol '+' stands for division, symbol '×' stands for subtraction, and symbol '÷' stands for multiplication. All other rules of mathematics are the same as in the existing system. What is the value of the following expression? 240 × 72 + 8 ÷ 24 – 6
Given: 240 × 72 + 8 ÷ 24 – 6 After replacing the signs from left to right and using the BODMAS rule, = 240 - 216 + 6 = 246 - 216 = 30 Hence, “30” is the correct answer.More Mathematical operation Questions
