If B>A, then which expression will have the highest value, given that A and B are positive integers.

$$\begin{gathered} \mathrm{B} > \mathrm{A} \\ \Rightarrow \mathrm{A} < \mathrm{B} \\ \Rightarrow \mathrm{A}-\mathrm{B}<0 \\ \mathrm{A}+\mathrm{B}>0 \mathrm{and} \mathrm{AB}>0 \end{gathered}$$
If A = 1, B = 4 then, AB < A+B
If A =2, B = 4 then, $\mathrm{AB} > \mathrm{A}+\mathrm{B}$
$\mathrm{Thus}, \mathrm{we} \mathrm{can}\text{'}\mathrm{t} \mathrm{say} \mathrm{which} \mathrm{one} \mathrm{of} \mathrm{A} + \mathrm{B} \mathrm{and} \mathrm{AB} \mathrm{has} \mathrm{higher} \mathrm{value}.$
