Exercise 1

Create two new variables called a, that has the value of 5, and b, that has the value of 3.

a = 5
b = 3

Subtract b from a and assign it to the new variable called difference

difference = a - b

Using the variables a, b and difference, print out the sentence that looks like:

The difference of 5 and 3 is 2

print("The difference of", a, "and", b, "is", difference)

The difference of 5 and 3 is 2

Exercise 2

How would you determine the data type on your_number and what data type is it?

type(your_number)

float

```

# Exercise 1

1. Create two new variables called `a`, that has the value of 5, and `b`, that has the value of 3.

```{python}
#| label: exercise_1_1
a = 5
b = 3
```

2. Subtract `b` from `a` and assign it to the new variable called `difference` 

```{python}
#| label: exercise_1_2
difference = a - b
```

3. Using the variables `a`, `b` and `difference`, print out the sentence that looks like:

```
The difference of 5 and 3 is 2
```

```{python}
#| label: exercise_1_3
print("The difference of", a, "and", b, "is", difference)
```

# Exercise 2

4. How would you determine the data type on `your_number` and what data type is it?

```{python}
#| label: exercise_2_4
type(your_number)
```
