The following equation is incorrect. Which two signs should be interc...

Explanation:

Given Equation:
12 + 8 - 25 ÷ 10 x 18 = 14

Interchanging x and - signs:
12 + 8 - 25 ÷ 10 - 18 = 14

Corrected Equation:
12 + 8 - 25 ÷ 10 - 18 = 14

Explanation:
Interchanging the x and - signs in the equation changes the order of operations. In the original equation, multiplication is performed before subtraction. However, in the corrected equation, subtraction is performed before multiplication, which follows the correct order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Therefore, by interchanging the x and - signs in the equation, we arrive at the corrected equation where subtraction is performed before multiplication, resulting in the correct solution.
