Please check your answer using more than the mnemonic. Search for “order of operations” to get the whole story.

Left-to-right, the answer is 288. ;-P

Both are correct, but the question is asked differently on each. One calculator is doing RPN (Reverse Polish Notation).

At first I thought 2 was the correct answer but --curiously, I think -- yours is a valid point because since division and multiplication are treated equally in terms of operational hierarchy, the recognized practice (absent parentheses) of solving the problem from left to right yields the 288 result.

Perhaps both are equally valid answers which means the solution is not determinable from the problem statement.
