    What does the term BODMAS mean?

    Community Answer
    BODMAS stands for Brackets, Order, Division, Multiplication, Addition, and Subtraction. Like PEMDAS, it is an abbreviation for the order of operations. In this case, Brackets stand for Parentheses; Order stands for Exponents (as in Order of Powers).

    When adding and subtracting (or multiplying and dividing) it's customary -- but not mandatory -- to work from left to right.

    How did you arrive at 25?
    Community Answer
    Twenty-five came from 5 squared, or 5x5. The 5 came from 8-3, and the 8 came from 6+2.
