'Addition' belongs to the word family of the verb 'addieren' (to add). If you know the verb, you can easily work out the meaning of the noun.

Can you add these two numbers for me, please?
In a mathematical context, 'Addition' is often mentioned together with the other basic arithmetic operations, especially 'Subtraktion' (subtraction). A fixed phrase is 'Addition und Subtraktion' (addition and subtraction).

In the general meaning of 'Hinzufügen' (adding), 'Addition' is mainly used in written language or in specialized contexts, such as chemistry or cooking. It sounds more formal than the simple word 'das Hinzufügen' (the adding).
Die Addition von Salz sollte erst am Ende des Kochvorgangs erfolgen.
The addition of salt should only take place at the end of the cooking process.
sum
'die Summe' and 'die Addition' both belong to calculating with numbers. But they are not the same thing. 'Addition' means the process or the arithmetic operation: you add numbers together. 'Summe' means the result of this calculation. Learners easily confuse the words because both appear in addition problems. A simple memory aid is: Addition is the method; the sum is the result.

Simon is practicing addition with two-digit numbers tomorrow.
Nach dem Rechnen steht die Summe unten auf dem Blatt.
