Doing your example using PEMDAS the answer would be developed as:
6/2(1+2) => 6/2*3 => 6/6 = 1

No, In the US, Multiplication and division have the same precedence so they're done left to right (as are addition and subtraction). Thus

6/2(1+2) Do the operation in parentheses first.

6/2(3) Of the remaining operators, division is the first, left to right so it is done in precedence over the multiplication.

3(3) There's only a multiplication left to do.

Implied multiplication has the same precedence as a multiply sign in most implementations.

A-HA (not the 'Take on Me' group)!!!! That's what I thought! Growing up in California, this US variation of PPMDAS, PEDMAS, left-to-right, Multiplication & Division have equal precedence to each other as do Add & Subtract makes more valid sense.

But, toml_12953, if your statement about implied multiplication is to hold, why does the Casio fx-115ES Plus calculate 1 for the problem?
