If ‘+’ means ‘×’, ‘×’ means ‘+’, ‘−’ means ‘÷’, and ‘÷’ means ‘−’, then what is the result of: 18 × 4 + 16 − 4 ÷ 3 = ?
Show answer & explanation
Correct answer: A
Explanation
'+' instead of '×'
'+' instead of '×'
'−' instead of '÷'
'−' instead of '÷'
Given equation:
18×4+16−4÷3
New equation after changing the signs:
18+4×16÷4−3
Now we will solve it using the BODMAS (Division, Multiplication, Addition, Subtraction) rule of mathematics:
Solving for division (÷): (16÷4=4)
18+4×4−3
Solving for multiplication (×): (4×4=16)
18+16−3
Solving for addition (+): (18+16=34)
34−3
Solving for subtraction (−): 31
