2m
property
Gather like terms: 2m - m + 3 + 4 = m + 7.
Yes. A simple example: sqrt(2)*sqrt(2) = 2 This property is used to "simplify" (rationalise the denominator of) surds.
commutative property of addition
6
2m
m7/2
m - 285 = 25.6 is simplified.
m3m6 = m3+6 = m9
property
the distributive property is only used when simplifying expressions or solving an equation: to write an expression just translate the question into symbols and letters - you don't need to use the distributive property or any other property for that

m3*m5 = m3+5 = m8
m-2+1-2m+1 When simplified: -m
Gather like terms: 2m - m + 3 + 4 = m + 7.
