27. teacher ?

i have just finished teaching simple mathematics to my my 7-year-old sister.
fiuhh. i'm so tired. and tension !
to teach a kid with no basic at all is more difficult rather than teaching a secondary school student.
seriously, trust me. at least, they know the basic of addition and subtraction.

okay. i helped my sister to do her mathematics homework, addition and subtraction.
she ask me, what is the answer for 27-11 ?
i teach her to use the 'bentuk lazim'.
then, when she did the question for 12-7, she did not know how to use the 'bentuk lazim'
and i had to think another solution for her.
i asked her to count started from 7 until 12 by using her fingers.
finally, she got the answer.

but, when it comes to question, 3+22,
here's the problem..
we only had 10 fingers. yes. only ten.
i asked her to use 3 fingers and counts started from 22,
but she asked me, why 3 ?
the question said, 3+22.. not 22+3 !

ohh. tiresome !
i had to give her few examples like, 2+3=5 and 3+2=5.
with little arguments since i lost my temper, (i'm not enough patience)
then, she started to understand and manage to answer the questions correctly.
but i don't think she's fully understand what i had teach her.


fuhh. i think, i'm not capable to be a teacher or lecturer.
maybe, i will bite my students.

till then,
