7 + (6 × 5^2 + 3) ?
Answer [A] 232  [B] 70 [C]160  [D] 41



Order of Operations - BODMAS

Operations
"Operations" mean things like add, subtract, multiply, divide, squaring, etc. If it isn't a number it is probably an operation.

How Do I Remember ? BODMAS !
   
B Brackets first
O Orders (ie Powers and Square Roots, etc.)
DM Division and Multiplication (left-to-right)
AS Addition and Subtraction (left-to-right)

The only strange name is "Orders". "Powers" would have been a better word, but who could remember "BPDMAS" ,  ? "Exponents" is used in Canada, and so you might prefer "BEDMAS", there is also "Indices" so that makes it "BIDMAS". In the US they say "Parenthesis" instead of Brackets, so they say "PEMDAS"

Oh, yes, and what about 7 + (6 × 5^2 + 3) ?
Answer [A] 232  [B] 70 [C]160  [D] 41
