Add Parenthesis to the operators section

Gameknight666

Hi Scratchers and Scratch Team,
I'm @Gameknight666, and I'd like Scratch to have parenthesis in the operators section of code. I want this because I want Scratch to be able to solve equations that have to do with the order of operations.
I'd really like to have it!
Regards,
Gameknight

You can already do this with what we have!

The equivalent of

 ( 1 + 2 ) * 3

in blocks is

Think of each block as having parenthesis around it

I see now. Thanks!

It would be really helpful if parentheses were actually drawn on the ends of the lozenges in the Operators section. Once you nest operators deeply enough, it's really hard to see how they fit together.

I also agree on that, because of the equation √(XX - XY)² + (YX - YY)² (AKA the equation for solving distance) (because I was working on a game and it needed the calculation of distance,) so that would be very helpful and useful!

Please post your suggestions in a separate topic.

I agree.

No support, you could just put different reporters together, because the OoO doesn't actually exist in scratch, and a reporter in another reporter gives the value of the first reporter with the second reporter

Well I'd say the that Order of Operations is much more explicit in Scratch than in other uses. Say if I asked you to calculate 1 + 2 * 3, then you implicitly apply the order of operations and do 2*3 first. However, in Scratch EVERYTHING has brackets around it, effectively, so it is nice and easy to see and manipulate the order of operations.

toch uses this:
1 + 2 * 3 // returns 7
in blocks is

but
( 1 + 2 ) * 3 // returns 9
is required for

as you can see, the scratch blocks have brackets in all cases, not just where they are required.

did you want to show the brackets on the blocks?

this is brackets
