# Hello, Python

1.

a. `6`

b. `20.0`

c. `4.5`

d. `-4.5`

e. `4`

f. `1`

g. `1.0`

h. `1.0`

i. `-1`

j. `-1`

k. `-4.5`

l. `19`

m. `35`

2. The unary plus operator returns the value of its argument unchanged.

3.

a. `temp = 24`

b. `temp = 1.8 * temp + 32`

4.

a. `(6 * 3)`

, then `(7 * 4)`

, then `(18 + 28)`

.

b. `(3 /4)`

, then `(5 + 0.75)`

.

c. `(3 ** 4)`

, `(2 * 81)`

, then `(5 - 162)`

.

5.

a. `x = 10.5`

b. `y = 4`

c. `x = x + y`

`x`

refers to `14.5`

and `y`

refers to `4`

.

6.

`(x - x)`

is evaluated, yielding`0`

.`0`

is added to the value at`x`

, which is`3`

, yielding`3`

.- finally the result,
`3`

, is assigned to variable`x`

.

7.

`4 + a`

8. b, e.
