Answer 2

That's a no-go, roscoe

Answer 3

a - {b - [c - (d - e) - f] - g}
a - {b - [c - d + e - f] - g}
a - {b - c + d - e + f - g}
a - b + c - d + e - f + g

Answer 5

a - {b - [c - (d - e) - f] - g}


a - {b - [c - d + e - f] - g} ... 1) See below


a - {b - c + d - e + f - g} ... 2) See below


a - b + c - d + e - f + g ... 3) See below




1) Distribute the negative through (d-e) to get -d+e


2) Distribute the negative through [c - d + e - f] to get -c + d - e + f


2) Distribute the negative through {b - c + d - e + f - g} to get - b + c - d + e - f + g
