If the digits \[\text{ }\!\!'\!\!\text{ 4 }\!\!'\!\!\text{ }\] and\[\text{ }\!\!'\!\!\text{ 8 }\!\!'\!\!\text{ }\], signs \[\text{ }\!\!'\!\!\text{ + }\!\!'\!\!\text{ }\] and \[\text{ }\!\!'\!\!\text{ - }\!\!'\!\!\text{ }\] are interchanged, then which one of the four equations would be correct?

• A. 4 + 8 - 12 = 16
• B. 4 - 8 + 12 = 0
• C. 8 + 4 - 12 = 24
• D. 8 - 4 + 12 = 8
