God, sometimes I love rereading messages. I tend to read half way through the message so I reread this message and saw the first part and thought “I wouldn’t write that”

#2246

I don’t read right to left for most math it’s just this addition proglem is easier right to left than it is left to right

#2247

Getting comfortable enough to do basic addition for the ones place from 01 to 9+9 is pretty useful. I tend to remember it from remembering other stuff. For example 78 is a really weird looking combination, so it’s 15.

#2248

And also 7+7 is 14 but shh

#2249

Multiplication is when I start to break numbers down into easier to compute forms if doing it by my head

#2250

60+15

But a prime must have 2 factors, so 1 can’t be prime.

prime number is defined as higher than 1…

(otherwhise negative 1 would be a prime as well)

I mean it’s not like the god of math descended upon us and said so it’s just how people define it because it’s more practical
