How to show more results in sagemathcell?

edit

Or simply

1+2, 10+20, 100+200

Or even

1+2,\
10+20,\
100+200

Thank you, FrédéricC and Juanjo. But your answers is not what I want. I wish the ouput has 3 lines. My example is for simplity, other example cannot be written as an array. Is there any other suggestion?

I don't know if you can configure your SagemathCell server to get what you want. Check the links given by @slelievre below your post. Anyway, you could rely on Python itself, saving results in variables and printing or showing them together at the end, like

a = 1+2
b = 10+20
c = 100+200
# and so on
output = [a,b,c] 
print ("{}\n"*len(output)).format(*output)

Thank you very much. I am working of @slelievre 's suggestion.
