Best ResponseYou've already chosen the best response.0Mnemonics are often used to help students remember the rules, but the rules taught by the use of acronyms can be misleading. In the United States the acronym PEMDAS is common. It stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. PEMDAS is often expanded to "Please excuse my dear Aunt Sally" with the first letter of each word creating the acronym PEMDAS. Canada uses BEDMAS and the UK uses BIDMAS or BODMAS. In Canada and other English speaking countries, Parentheses may be called Brackets, or symbols of inclusion and Exponentiation may be called either Indices, Powers or Orders, which have the same precedence as Roots or Radicals. Since multiplication and division are of equal precedence, M and D are often interchanged, leading to such acronyms as BODMAS.  Wikipedia

Best ResponseYou've already chosen the best response.0Both a rhombi and squares have 4 equal sides. However, a square must have 4 right angles. While a rhombi do not need 4 right angles. Rhombi simply need to have 4 equal sides. Therefore, a square is a rhombi but a rhombi is no necessarily a square.
