# Complicated Math

This section contains intriguing information; I trust you will find it engaging. You may have encountered mathematical operations such as `//`

or `%`

. In this section, we will delve into their explanations.

The operation `//`

is called **integer part division**. It assists in determining how many whole instances of the right-hand number can be accommodated within the left-hand number. A common application of this operation is in scenarios where we wish to calculate the number of identical items we can purchase. For example, if we possess `38`

dollars and intend to purchase multiple bottles of water, each priced at `7`

dollars, we can calculate `38//7`

, yielding a result of `5`

. Thus, we can purchase 5 complete bottles.

The second operation, denoted as `%`

and called the **remainder**, serves a similar purpose. In practical terms, the remainder can be likened to the concept of change. To illustrate this, let's revisit the bottles example. If we determine that with `38`

dollars, we can purchase `5`

bottles of water, the remainder reveals the amount of change remaining after we acquire the maximum possible quantity of items. In the same scenario, our change is calculated as `38 % 7`

, resulting in 3. Consequently, we have spent 35 dollars and retained 3 dollars as a change.

Task

Imagine that you are a student at school and you have to solve `10`

math tasks. You’ve noticed that the average time to handle each task is `7`

minutes; however, you have `60`

minutes total.

- Calculate how many tasks you can manage and assign the result to the
`completed`

variable. - Calculate the number of minutes left and assign the result to the variable
`minutes`

.

Complete the task using the `//`

and `%`

operations, one operation for one task.
