Question

Choose 2 axioms that allows 22 + (m + 8) to be written as m + 30

Answer 1

Communitivity and Associativity I believe ( i know i spelled those wrong)
Because addition is communitive:
\[22+(m+8)=(m+8)+22\]

Answer 2

Then because addition is associative:
\[(m+8)+22=m+(8+22) = m+30\]

Answer 3

a+(b+c) = (a+b)+c

a+b+c = a+(b+c)
