2. Anyone who gives you a different answer needs to revise the order of operations.

Do you mean

5 + (4 × 15) - (21 × 3)

Or

5 + (4 × 15 - 21) x 3

?

According to the order of operations, it’s effectively the first one.

It is actually a set of numbers, interspersed with symbols.

As a mathematical expression it is unanswerable without brackets to denote the order of the operators could be -432 +342 or +2

Next?

Its the first one. And the answer is 2.

BODMAS!

.

1. Brackets & Orders (like 3²)

2. Division & Multiplication

3. Addition & Subtraction

.

For each of the latter categories, it’s best to essentially convert division into a multiplication (so 10 ÷ 5 is 10 x 1/5, etc.) and subtraction into an addition (so 10 - 5 is 10 + (-5)).

.

In the above instance there are no brackets or orders, so we do the multiplication first, which gives us 60 and 63. So then it’s 5 + 60 - 63. So the answer is 2. Accept no other answer.

Its actually bidmas now. They've change the order to indices.

It's leaking. Sponges do that as they fill up.

Anyway, my last mathematics class was almost 40 years ago; how am I supposed to remember that far back when I can't remember stuff from yesterday

Question.... we read left to right, and have priority weighting on operators of (, x ÷, + -

Is that globally true? I.e. do Chinese or Arabic countries apply the same mathematical order?

Never do mental arithmetic while you're making toast.

Not found a definitive answer though found a statement that long ago Chinese wrote equations top to bottom, which would indicate they may now copy the western left to right format.

The way it's written doesn't really matter as long as it is consistent as the way a formula is written down will be defined by whatever system is in use. The order of operators however must be the same.
