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 - Nov 23rd 2008, 03:00 AMLonehwolf
BODMAS

Brackets

Of

Division

Multiplication

Addition

Subtraction

$\displaystyle (3+3)(2)(3)^3+1$

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

$\displaystyle (6)(2)(3)^3+1$

When you have a power ( $\displaystyle (3)^3$ ) 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

$\displaystyle 3^3$ = 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 ;) - Nov 25th 2008, 09:20 PMErdos32212
