What's the answer? (325 x 2) + (757 + 316) ÷ by 4 I am NOT MATHMATICALLY INCLINED! I get 430.75...but some others are saying 918.25....I'm guessing I'm probably wrong...am I?

I also get that! Heres a neat little hint Parenthesis Exponents Multiplication Division Addition Subtraction Addition/Subtraction and Multiplication/Division are which ever of the two come first. Please excuse my dear aunt sally!

(325 x 2) + (757 + 316) ÷ by 4 That would be 650. (325 x 2) + (757 + 316) ÷ by 4 That would be 1073 which you need to divide by 4, hence the result is 268.25 Add the blue numbers and you get 918.25

This is why I was never good with math. give me some wood and I'll build you a guitar... give me a math problem... and I'll give you some problems of your own. :mrgreen:

ok...so who's going to explain we the convolution of two signals? heres the equation: the equation is easy...and so is the explanation of two dimensional convolution (for example in photoshop)... but what for is it in maths?
