100 days divided by 7 days to a week gives you 14.2 weeks

You should explain that we have to multiply the decimal part with 7 to get the exact answer (1.4 day). If it was 101 days, the division would make 14.42857, I'm afraid people are going to think that the answer was 4 days; even worse, 5 days.

mod is used to find the remainder like 5 mod 2 = 1 bec the biggest multiply less than 0 2*2=4 then 5-4=1

Basically, you have numbers starting from 0.

0-Mon

1-Tue

2-Wed

3-Thur

4-Fri

5-Sat

6-Sun

7-Mon

You can either count up from sevens until you get to the number thats the highest before 100 or you can do 100 divided by seven, with a remainder of 2. The answer is 98. You know that 98 is a Monday because when you count up by sevens, every number that you count on will be a Monday. However, 98 is still not 100. You need to count up one day for every number.

98-Mon

99-Tue

100-Wed

Therefore Wednesday is the answer.

After seven days have passed, it will be Monday again. So, we want to divide 100 by 7 and take the remainder.

100 mod 7 = 2

This means that 100 days from Monday is the same as two days from Monday. Therefore it will be Wednesday.

100 % 7 = 2 (NOTE THAT % MEANS MODULUS, NOT DIVISION). Monday + 2 = Wednesday.

When 100 is divided by 7, the remainder is 2. That is, $100 \equiv 2 \pmod{7}$ . Hence, 100 days from now is the same as 2 days from now. Two days after Monday is a

Wednesday.
