If '+' = '-' and '-' = '×', find the value of:

$12+4-3=?$

Correct Answer: The correct answer is 0.

Step-by-step explanation:

Step 1: Identify the operator replacements
According to the given problem instructions, we are required to interchange the mathematical operations as follows:
• The plus sign ($+$) is replaced by a minus sign ($-$).
• The minus sign ($-$) is replaced by a multiplication sign ($\times$).

Step 2: Rewrite the expression with new operators
The original mathematical expression given in the question is:

$12+4-3$

Replacing '+' with '-' and '-' with '×', the new expression becomes:

$12-4\times 3$

Step 3: Apply the order of operations (BODMAS/PEMDAS)
In standard mathematics, multiplication must be performed before subtraction.

First, calculate the multiplication:

$4\times 3=12$

Next, perform the subtraction with the result obtained:

$12-12=0$

Therefore, the value of the expression is 0.
