Where they differed most

The task — Mnemonic that works

Create a mnemonic for the order of operations (brackets, indices, division/multiplication, addition/subtraction) that is NOT 'BIDMAS/BODMAS' spelled out, plus one sentence on when the D/M order actually matters.

Mnemonic: **“Group first, raise powers next, then work left-to-right through × and ÷, and finally work left-to-right through + and −.”**

The **division/multiplication order matters only when they appear together in a chain**, because they have equal priority and must be done **from left to right**—for example, \(12 ÷ 3 × 2 = 8\), not \(2\).
**Mnemonic:** “Brave Inventors Design Machines After School.”  
**D/M rule:** Division and multiplication have equal precedence, so when both appear in the same chain, calculate from left to right.
