Simplify the following expressions by removing the brackets and finding their values.

Since there is a '+' sign before the bracket, the signs of the terms inside remain the same. $14 + 12 + 10$

$$
26 + 10 = 36
$$
The expression is $\boxed{14 + 12 + 10}$, and its value is $\boxed{36}$.

• b) $14 - (12 + 10)$

Since there is a '-' sign before the bracket, the signs of the terms inside change. $14 - 12 - 10$

$$
2 - 10 = -8
$$
The expression is $\boxed{14 - 12 - 10}$, and its value is $\boxed{-8}$.

• c) $14 + (12 - 10)$

Since there is a '+' sign before the bracket, the signs of the terms inside remain the same. $14 + 12 - 10$

$$
26 - 10 = 16
$$
The expression is $\boxed{14 + 12 - 10}$, and its value is $\boxed{16}$.

• d) $14 - (12 - 10)$

Since there is a '-' sign before the bracket, the signs of the terms inside change. $14 - 12 + 10$

$$
2 + 10 = 12
$$
The expression is $\boxed{14 - 12 + 10}$, and its value is $\boxed{12}$.

• e) $-14 + (12 - 10)$

Since there is a '+' sign before the bracket, the signs of the terms inside remain the same. $-14 + 12 - 10$

$$
-2 - 10 = -12
$$
The expression is $\boxed{-14 + 12 - 10}$, and its value is $\boxed{-12}$.

• f) $14 - (-12 - 10)$

Since there is a '-' sign before the bracket, the signs of the terms inside change. $14 + 12 + 10$
