Without any equality signs the given terms can't be classed as equations.
5n + 3m This has an unknown value without more information. If you know the value of n and m then you can substitute and get a value for the expression.
It is an algebraic expression which cannot be evaluated without information about m.
3m*3m*2m=300*300*200=18,000,000cm3
It is 9m^2 - 9 = (3m + 3)*(3m - 3).

9m + 9m + 3m + 3m = 24m
240 m3 - without using a calculator !
-3m + 8 - 7 = -3m + 1
5m+3=3m+9 5m+3-3=3m+9-3 5m=3m+6 5m-3m=3m+6-3m 2m=6 (2m)/2=6/2 m=3
3m*3m*2m=300*300*200=18,000,000cm3
