If + means − , − means × , × means ÷ , ÷ means +, what will come in place of the question mark (?) in the given equation?
22 × 11 – 450 ÷ 50 + 500 = ?

The correct answer is 450.

According to the question, the mathematical symbols are interchanged as follows:
• + means −
• − means ×
• × means ÷
• ÷ means +

Original Equation:
$22\times 11-450÷50+500=?$

Substituting the given operator signs into the equation, we get:
$22÷11\times 450+50-500=?$

Now, follow the BODMAS rule (Brackets, Orders, Division, Multiplication, Addition, Subtraction) to solve the equation step-by-step:

Step 1: Perform Division ($22÷11$)
$22÷11=2$

The equation becomes:
$2\times 450+50-500$

Step 2: Perform Multiplication ($2\times 450$)
$2\times 450=900$

The equation becomes:
$900+50-500$

Step 3: Perform Addition ($900+50$)
$900+50=950$

The equation becomes:
$950-500$

Step 4: Perform Subtraction ($950-500$)
$950-500=450$

Hence, the value in place of the question mark (?) is 450.
