Answer 2

I understand that you want me to answer in detail the given expressions: a) a + (a + b); b) a + b + c; c) a - b - c; d) a + b - c; e) (a + b) + a; f) a + (a - b). Here is my response:

a) a + (a + b) = a + a + b = 2a + b. This expression is the sum of two terms: 2a and b. The coefficient of a is 2, and the constant term is b.

b) a + b + c = a + (b + c). This expression is the sum of three terms: a, b, and c. The coefficients of a, b, and c are 1, 1, and 1, respectively. There is no constant term.

c) a - b - c = a - (b + c). This expression is the difference of two terms: a and b + c. The coefficient of a is 1, and the coefficient of b + c is -1. There is no constant term.

d) a + b - c = a + (b - c). This expression is the sum of two terms: a and b - c. The coefficient of a is 1, and the coefficient of b - c is 1. There is no constant term.

e) (a + b) + a = a + b + a = 2a + b. This expression is the same as the expression in a), but with a different order of addition. The order of addition does not affect the result, because addition is commutative and associative.

f) a + (a - b) = a + a - b = 2a - b. This expression is the difference of two terms: 2a and b. The coefficient of a is 2, and the constant term is -b.

I hope this helps you understand the expressions better. If you want to learn more about algebra, you can check out some of the web search results I found for you . Have a nice day!
