## Variables in Programming and Algebra Comments

• #### Matthew

Easy I'm liking this website.

I expected to have to answer something like sum == answer; You just have to enter the answer itself

• #### Learneroo

@Geert, I clarified that looking for number.

• #### Jamison Norwood

I love this site. Now every other book is looking like a reference sheet.

• #### Brent Jones

You say "In the following code, what number will sum equal?"
It would be better to say "In the following code, what number will sum become?"
Also, you should give an extra example of multi-line assignment of variables before testing student understanding

Thanks to this website, I dont feel like a dumb as.. anymore!

• #### xiaochayou

so good, I like it so much!

• Good site so far :)

It's easy. Forget the int x = 2 and go to x = 100 and add the y to the x.

immidiately = immediately

I have increased my programming knowledge by 500% in the last 10 minutes.

• #### Gomati Damle

In the code why it is written
int x = 2;
int y = 5;
x = 100; .Can anyone tell me why data type int is not written befor x=100;

• #### Learneroo

As mentioned on the previous page, you need to declare a variable's type the first time, but afterwards you can use it without re-mentioning what type it is.

• #### thales

Yes, but i want to learn programming. And isnt this a bit to easy to really learn programming?

• #### Learneroo

You can start off easy. There's lot's of challenging material later if you want it!

• #### thales

ok i want that challenging stuff :-)

• #### Learneroo

When you're ready, check out Algorithms

• #### thales

we will, but we are not ready yet :-)

• #### Heckingson Jumbo

this is just like js and c

• #### Dion Matthew Levy

This was my hardest challenge yet...How does 100 + 5 = 105 if x=2???? Computers are DU|\/|@\$\$3\$ !!!! If X(2)=100 And X(1)=2 and Y(5) then wouldn't x+x+y =107? the only place xxy ever made sense was in Klinefelter syndrome! :p

Thanks.

Got confused here since x = 100; wasn't given any data type.
