    Just remember the order of operations:
    Parentheses
    Exponents
    Division/Multiplication
    Addition/Subtraction

    Better known as PEMDAS

    therefore
    (3+3)(2)(3)^3+1
    do parentheses: (6)(2)(3)^3 +1
    do exponents: (6)(2)(27) + 1
    do division/multiplication: 324 +1
    do addition/subtraction: 325

    BODMAS

    Brackets
    Of
    Division
    Multiplication
    Addition
    Subtraction

    (3+3)(2)(3)^3+1

    Make sure all brackets are worked out (notice the {3+3})

    (6)(2)(3)^3+1

    When you have a power ( (3)^3 ) understand that that power is tied to just naything before it in brackets, so since there's a bracket containing 3 before it, you cube that number

    3^3 = 27

    So right now we're like this:

    (6)(2)(27)+1

    Addition is at the bottom of BODMAS, so that's kept for last

    (6)(2)(27)
    (12)(27)
    324

    But don't forget that little +1 at the end...
    so 324 + 1 = 325

    Practice using BODMAS, try making your own questions, and don't worry about getting it wrong, as long as you're trying, you'll improve greatly in mathematics
