## How to change the world!


change the world -> change your heart

-> change your perspective -> change your action

-> every time you face a realm, stay mindfulness

-> every time you face a realm, observe your 

afflictions(negative thought)


nagative thought: your math is bad

-> what is the definition of having a bad math

## Homework Review

### Practices

==Learn to explain the questions and your code to others==

You need to prepare your code and practice your explanation at home. And, you will explain the question, your solving logic, and your code in class ^^

- Jason :[Adding Factorials](https://snakify.org/en/lessons/for_loop_range/problems/sum_of_factorials/)
- Janet : [Ladder](https://snakify.org/en/lessons/for_loop_range/problems/ladder/)
- Sophia: [Series - 2](https://snakify.org/en/lessons/for_loop_range/problems/series_2/)

==Programming Questions==

**Q1. First N even, descending**

Given an integer N, print all the even numbers from 0 to N in descending order.

- Input
> test 1: 8
> test 2: 11
- Output
> test 1: 8, 6, 4, 2, 0
> test 2: 10, 8, 6, 4, 2, 0

**Q2. Squares in range**

Given two integers A and B, print squares of all integer numbers between them, as shown below. There shouldn't be any spaces around * and =. The sep argument of the function print() may help you with that.


### OMAK

- Audio file
- OMAK notes(just as usual)

Record one of your past memory in the past, and tried to do the OMAK to it using your personal style ^^

## Homework

### Practices

==Learn to explain the questions and your code to others==

Janet please explain "Ladder" problem to Sophia, and we will let Sophia to explain the "logic of her code", and "the actual code in the class."

==Programming Questions==

**Add Primes in range**

Add up all the prime numbers in the range

- Input
> test 1: 5, 10
> test 2: 5, 20
- Output
> test 1: 12
> test 2: 72

ans = 0

for num in range(5, 11):
    primeflag = 1
    
    # check if it is the prime number
    for divisor in range(2, num):
        if (num%divisor == 0):
            #print(num, divisor)
            primeflag = 0
            #print("="*8)
    
    if primeflag == 1:
        ans = ans + num
        #print(num , ans)

print(ans)

### OMAK

#### Writing an OMAK of your sibilings

- Your good deeds toward him/her
- Her good deeds toward you/others
- A lovely memory with a picture

#### New way of storytelling
- Story Audio file upload to youtube
- Play it using livecoding
