Evaluate the following arithmetic expressions: b) (-10) + 15, c) +100 + 40 - 30, e) 5 ", -3, f) (-144) ", 12 10. Work out: b) -90 15 ", 5 - 45 + 32, d) 55 + 48 ", 6 - 11 7, f) 12 150 ", 15 - (4 + 52).

$$-10 + 15 = 5$$

The result is $\boxed{5}$.

c) $+100 + 40 - 30$

$$140 - 30 = 110$$

The result is $\boxed{110}$.

e) $5 \div -3$

$$5 \div -3 = -\frac{5}{3}$$

The result is $\boxed{-\frac{5}{3}}$.

f) $(-144) \div 12 \times 10$

$$-12 \times 10 = -120$$

The result is $\boxed{-120}$.

2. Work out:

b) $-90 \times 15 \div 5 - 45 + 32$

$$-315 + 32 = -283$$

The result is $\boxed{-283}$.

d) $55 + 48 \div 6 - 11 \times 7$

$$63 - 77 = -14$$

The result is $\boxed{-14}$.

f) $12 \times 150 \div 15 - (4 + 52)$

$$120 - 56 = 64$$

The result is $\boxed{64}$.

h) $70 - 50 \times 95 \div (14 + 5) + 21$

$$-180 + 21 = -159$$

The result is $\boxed{-159}$.
