Visual Basic.NET Programming. Beginner Lesson 8. Complex Arithmetic Expressions

This is the eighth in a series of computer science video tutorials for beginners, about programming with Visual Basic.NET (VB.NET) in Visual Studio. In this lesson, you will learn how to write complex arithmetic expressions that perform calculations in your code. A complex arithmetic expression is an expression that involves more than one arithmetic operator. You also will learn how to control the order of operations using brackets, also known as parentheses. You will see that the order of operations in a complex expression is given by the acronyms BODMAS (Brackets Order Division Multiplication Addition Subtraction) and PEMDAS, Please Excuse My Dear Aunt Sally (Parentheses Exponentiation Multiplication Division Addition Subtraction).

By far best explanation I found for beginners

[@SkepticleOrc]

A bit of good old fashioned Bodmas. Love it.

[@ComputerScienceLessons]

Indeed. And don't forget to 'Please Excuse My Dear Aunt Sally' :)KD

[@jtlunsford780]

I got that, but it's sure nice to be reminded. And now, I've heard of BODMAS. Thank you for what you do and how you do it....JT

"50 pounds worth of cakes. No surprises there." You have become the man from the math textbooks.

[@ComputerScienceLessons]

Perhaps it was a school teacher buying cakes for his students :)KD

Life saver . God bless you

[@StephenBoyd21]

I think I've been to Pemdas on holiday, isn't it in Wales?

[@ComputerScienceLessons]

It's got that ring to it. Might be in Pembrokeshire. There's a Pemdas near San Jose - do you know the way?

[@TempleTrainer]

Yeah PEMDAS is the better example Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction

[@ComputerScienceLessons]

I prefer it to BODMAS :)KD

[@braddenton1350]

Thank you!

[@ComputerScienceLessons]

and thank you too :)KD

8:03 Why no.2 and no.3 are different if Division is perform first? 1. iResult = 10 / 5 * 2 2. iResult = 2 * 10 / 5 3. iResult = 10 * 5 / 2

[@nationalshitpostagency]

multiplication and division have equal priority so performing of the operations go through left to right. 2. (2*10)/5 3.(10*5)/2. 4:20

i really wouldnt mind being payed £15 for some cakes

[@kevinerose]

What does everyone call these? I call (these) parenthesis and [these] brackets and I call {these} braces. ( ) , [ ] , { }. I am from USA. What do you say and where are you from? thanks.

[@ComputerScienceLessons]

Hi Kevin. I call (these) brackets, or round brackets and occasionally parentheses (strictly speaking a parenthesis is a word, clause, or sentence inserted as an explanation or afterthought into a passage which is grammatically complete without it). I call [these] square brackets and {these} are curly brackets. Let's not forget . :)KD

It's quite obvious he is british, like me.

@@lucadoesthings does that matter where he is from, he is doing good work (don't take it as offensive)
