# Cultural Mnemonics

I was browsing through an American study guide and it recommended remembering the order of arithmetic operations through this mnemonic:

PEMDAS (Please Excuse My Dear Aunt Sally) –
Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Locally, I learnt and teach kids this:
BODMAS -
Brackets, Order, Division, Multiplication, Addition, Subtraction.

According to this wiki page, this is the UK way.

Another interesting one is
SOHCAHTOA – for the three trigonometric functions.
Locally, we teach students to remember “Toa Cah Soh” which in a local dialect actually means Big Feet Aunty.

I’ve learned a mnemonic for the recomended order of the function to integrate, it is (in spanish) ILATE for: Inversas, Logarítmicas, Algebraicas, Trigonométricas y Exponenciales.

SOHCAHTOA = ‘Some Old Houses Can Always Hide Their Old Age’ and there are variants: Some Old Hags etc…’
