Is there ever a situation where you shouldn't use BODMAS?

Not when calculating with numbers, it should always be used.

No, you should always use BODMAS.

No, always use BODMAS.

For the content covered in secondary education i.e up to A-level Further Maths, we should always use BODMAS. However, when we get to more complicated mathematical structures i.e not the set of reals, there may be instances when BODMAS cannot be used, but those instances will define not to use it if this is the case.

Never. BODMAS is always the order of operations.

yes, for example if we do not use brackets or exponents but just use a simpler expression like 1-3+2. If we generally follow BODMAS, the answer is incorrect

BODMAS/BIDMAS (brackets, indices or orders, division, multiplication, addition, subtraction) should always be applied in this order when solving any tasks is maths.

YES. In BODMAS you should do addition first but if only subtraction and addition are in the question then you must do the subtraction first.

There aren't really any exceptions to the BODMAS hierarchy but there are a couple of special cases involving the order of the calculation.

One is where you get an exponent inside a bracketed part of the calculation, such as:

25 + (5 × 4^2+ 7)

Although brackets would usually come first over orders. Within the bracketed part of the sum, the orders(the squared number) takes priority over everything else so we resolve that first.

25 + (5 × 16+ 7)

You would then complete the calculation as normal.

Actually no! Every situation should rely on this convention.

Well, BODMAS is limited to simple Algebra and fractions.

There may be times when solving simultaneous equations where it is easier to collect like terms first. Therefore you would do addition before multiplication, however, when it comes to solving the equation you would still use BODMAS. That is always the correct order to solve an equation.

If BODMAS, doesn’t work. Try BIDMAS. Same approach same correct answer :)
