In some countries we're taught to treat implicit multiplications as a block, as if it was surrounded by parenthesis. Not sure what exactly this convention is called, but afaic this shit was never ambiguous here. It is a convention thing, there is no right or wrong as the convention needs to be given first. It is like arguing the spelling of color vs colour.

BDMAS bracket - divide - multiply - add - subtract

afair, multiplication was always before division, also as addition was before subtraction

~~Multiplication VS division doesn't matter just like order of addition and subtraction doesn't matter.. You can do either and get same results.~~

Edit : the order matters as proven below, hence is important

If you do only multiplication first, then 2×3÷3×2 = 6÷6 = 1.

If you do mixed division and multiplication left to right, then 2×3÷3×2 = 6÷3×2 = 2×2 = 4.

Edit: changed whitespace for clarity

4 would be correct since you go left to right.

BEDMAS: Bracket - Exponent - Divide - Multiply - Add - Subtract

PEMDAS: Parenthesis - Exponent - Multiply - Divide - Add - Subtract

Firstly, don't forget exponents come before multiply/divide. More importantly, neither defines wether implied multiplication is a multiply/divide operation or a bracketed operation.

Exponents should be the first thing right? Or are we talking the brackets in exponents..

Brackets are ALWAYS first.

I will never forget this.
