Hello and welcome to my series called Math tutorials I will do it every week
today We will do a 9 trick
To do this trick you have to count back one from the number
We are using this number for instance five
will be
16 like like take away would like 5 minus 1 is 5
Wait, no, no, not 16
14 yeah and 6 is 13
15 oops
So like that
I'm in a mistake. But if you use 9, it would not work like that
9 Plus 9 is
Actually would because 9 months one. It's 18
Huh?
That's interesting
but I'll do this every week and this is the first one of the series so
I'll see you next time. Bye
