@@niktambar5324 nah recruitment guy sorta fucked me over at the very last minute (literally the day before) by telling me my key-skills wasnt a C equivalent (so the role i was applying for would not be available to me, even though i have a degree lul) so I have to re-sit before applying again. and covid is making that really hard, nobody is taking on private students to re-sit right now.

How did he get 110?

[@kowsaladevithevanarandran6121]

Because when it was 220 you could times it by 2 and 110 that is how he got it

What if you divide 7 by 7. 7 is a prime number isnt it

[@kowsaladevithevanarandran6121]

A prime number is a number that can only be divided by itself or one and you did by it self so no we couldn’t do that😊

[@graceharrison3122]

But why split it into 110 and 2 like there’s no explanation

[@wow2680]

Sorry if this is a bit late 110 × 2 = 220 right? So we will put 2 on our list for now List: 2 55 x 2 is 110 so we will put another 2 on this list. The reason why we aren't putting these big numbers on it yet is becauss they aren't prime, you can only put prime numbers on the list. List: 2 × 2 Now, because we can't half 55 without getting a number with decimals, we have to find a number that is prime and also goes into 55. Lets do 5 x 11 which is 55. 5 and 11 are both prime so let's add them to the list. List: 2 x 2 x 5 x 11 If we solve this, the answer is 220! Simple as that. Here is the tree method: 220 / \ 110 2 / \ 55 2 / \ 5 11 2 x 2 x 5 x 11= 220
