So after a little more looking and learning, and help from friends, I have a new sentence.
ⲙⲉⲧⲣⲱⲙⲓ(Humankind) ⲥⲉⲟⲛϧ(they live) ⲉ̀ⲑⲣⲟⲩϣⲓⲛⲓ(in order/so that/for they seek) ⲡ̀ⲉ̀ⲙⲓ(the knowledge) ⲉⲧϫⲏⲕ ⲉⲃⲟⲗ(which is complete) ⲛ̀ⲧⲉ(of) ⲡϫⲓⲛⲱⲡ(the act of calculations).
ⲙⲉⲧⲣⲱⲙⲓ, ⲥⲉⲟⲛϧ ⲉ̀ⲑⲣⲟⲩϣⲓⲛⲓ ⲡ̀ⲉ̀ⲙⲓ ⲉⲧϫⲏⲕ ⲉⲃⲟⲗ ⲛ̀ⲧⲉ ⲡϫⲓⲛⲱⲡ.
I replaced ⲥⲱⲟⲩⲛ with ⲉ̀ⲙⲓ, since I think ⲉ̀ⲙⲓ is used for general knowledge, while ⲥⲱⲟⲩⲛ is used for more specific knowledge. Do you think this change is good, or bad?
Also, if you can find anything else wrong with the sentence, please let me know. Thank you!
