Ummm if I understand the question there will be symbols.

Addition is +
Subtraction is -
Multiplication is * or x
Division is /

If you have an expression use PEMDAS like ChrisR described.

PEMDAS is very helpful to remember when thinking of order of operations. Parentheses, Exponents, Multiply, Divide, Add, then Subtract. Always in that order. 

If you are talking about something more specific you may want to give a bit more information.

What is m∠Q ?
ddd [48]
Unlike the previous problem, this one requires application of the Law of Cosines.  You want to find angle Q when you know the lengths of all 3 sides of the triangle.

Law of Cosines:  a^2 = b^2 + c^2 - 2bc cos A

Applying that here:

                           40^2 = 32^2 + 64^2 - 2(32)(64)cos Q

Do the math.  Solve for cos Q, and then find Q in degrees and Q in radians.
