I heard this as "die Sonne ist gut" meaning the sun is good. Is it just me?
I hear "Summe", not "Sonne". But it would be better if the sentences were spoken by a real person, not by a machine.
Sounds fine to me.
I heard the same thing!
Does "die Summe" mean sum as in "total", or sum as in "mathematical calculation", or both?
For example, in English, 2x7=14 (a product) is a sum (calculation), but not a sum (total). Ist es ein Summe?
You can use it for an amount of money or for an addition. 2*7 is a "Produkt", not a "Summe".
