Is Bodmas wrong?

Wrong Answer

This would be a really useful algorithm if it worked in every situation, but consider the much simpler expression 1 – 2 + 4 . It doesn’t contain parentheses, powers, divisions or multiplications, so we follow BODMAS and do the addition followed by the subtraction: This is wrong.
