some of the equations are provided below with symbols and mathematical relations you have to check which of the following combination is correct If A ✚ B = (A × B) - (A + B), what is 6 ✚ 3?
9
9 is correct.
The symbol ✚ is a new operation defined as \(A ✚ B = (A \times B) - (A + B)\), where + inside the brackets is ordinary addition.
Put A = 6 and B = 3: \(6 \times 3 = 18\) and \(6 + 3 = 9\).
\(6 ✚ 3 = 18 - 9 = 9\).
The symbol therefore does not mean ordinary addition here; reading it as plain addition would wrongly give 6 + 3. The defined rule must be applied exactly as stated.
Hence, the value is 9.
