I'm a beginner German learner and a mathematician. I've been trying to write solutions to simple linear algebra questions in German in order to practice writing mathematics in German. I keep on having problems when I would usually use a word in English ending in "-ing".
Could someone help me translate the following two phrases:
"By summing both sides of equations (1), (2) and (3) and dividing by 3, we get:"
"Using equation (1), we get:"
Thanks for any help. Conrad
