I am beginner simulink how can i split the way I wrote in blue pencil 1=2+3 I try demux but it has error

[Ameer Hamza]

What do you mean by splitting "1=2+3". You need to elaborate on this point further.

[Bahadir Celiktas]

the sum of two signals on the output needs to give the signal on the input output signals 2 and 3 input signal 1

[Ameer Hamza]

There are many ways that the sum of two outputs is the same as the input. How do you want to calculate two outputs? For example, if the output is 1, then I can add 1000000 and -999999, and the output is still 1.

I think you dont understand me if you look at screenshot you understand 1,2,3 are symbolic expression

Answer 1

[Ameer Hamza]

You can create a model like this. The sum at (2) and (3) will be same as (1)
