8 - Counting, Numbers and Arithmatics (PSE)
8 - Counting, Numbers and Arithmatics (PSE)
We will do something different today.
We will talk about counting and numbers and some arithmatics in English.
How do we say 1, 2, 3, ..., 10 in English?
How do we say 11, 12, 13, ... in English?
(Excellent!)
Now, how do we say 20, 21, 22, 23 ... in English?
(You have done it before!)
Now, how do we say 30, 40, 50,..., 100, 1000, 10,000 in English?
And, how do we say 101, 102, 510, 1001, 1020, 1925, 10,101 in English?
(Excellent! You already know how to count and say numbers.)
How do we read these?
0 ('nought', 'oh', 'zero', all are correct)
0.001 ('zero point zero zero one' or 'oh point oh oh one', but 'mixing zero and oh' is not good.)
1.50 (one point five oh)
0.6702 (oh point six seven oh two)
10% (ten percent)
$20 (twenty dallars)
5K ('five kay' ; K usually means kilo or 1,000)
1/2 (one half or 'one on two')
2/3 (two thirds or 'two over three')
3/4 (three quarters or three out of four)
1/5 (one fifth or 'one over five')
7/10 ('seven over ten' or 'seven out of ten')
(Very good. We will move on.)
How do we read these?
+7 (plus พลัซึ seven)
-5 (minus ไม นัซึ five)
1 + 2 = 3 ('one plus two equal อี ควอวลึ three')
8 - 4 = 4 ('eight minus four equal four')
2 x 3 = 6 ('two time three equal six')
10 / 5 = 2 ('ten divided by five equal two' or '10 over 5 equal 2')
(3+6)/3 = 3 (three plus six divided by three equal three)
How about these?
2 > 1 (two greater than one)
5 < n (five less than en)
X = 3 (egs equal three)
Just for fun, we'll 'do arithmatics in our head'(คิดในใจ).
But please say the answer out loud.
1.50 plus 3
24 minus 7
15 times 5
32 divided by 8
add 1.50 to 3
multiply 5 by 15
subtract 7 from 24
Do we have enough numbers and arithmatics for one day?
[Dear Teachers,
Teaching arithmatics in English is not difficult.
Children can learn arithmatics in English in a few hours.
With a few more programming words, children can learn to program computers (in a few hours).
They can learn about mathematical concepts and objects.
Sciences and Technologies stand on Mathematics. All use English as the common language.]
[Joke: We heard a reporter told us on television during the flood "twenty thousand pigs were washed away". In fact, he meant "twenty sows and pigs..." ;-) ]

Very useful ! I have to bookmark this post. Looking forward for having the E-book "PSE" soon.
May I have a trivial question.
(3+6)/3 = 3 (three plus six divide by three equal three)
How to say different (3+6)/ (3+6) and (3+6)/3 + 6
PS. 2x2 in some medical records read secondary to..
for example, Pneumonia 2x2 aspiration :-)
Thank you Doctor ป. -- you spotted another typo for me ;-)
Your question is one that prompts mathematicians to defend their special language with extra emphasis on precision.
(3+6) + (3x2) / (11- (3x2)) would be read:
in precision "open bracket three plus six close bracket plus o.b. three times two c.b. divided by o.b. eleven minus o.b. three times two c.b. c.b"
In normal English " in brackets three plus six 'then' plus in.b. three times two 'then' divided by in.b. eleven minus in.b. three times two"
As we can hear (if we read the math expression out loud) we have only 'small pauses' between words, not enough to visualize the expression at all. Many symbolic expressions in mathematics, programming and 'jargon' (in medicine, etc) are NOT ALL spoken languages (but shorthand?).
Notes: there are many types of brackets แบรคเคทซึ
o.b. = open bracket, c.b. = close bracket, in.b. = in brackets
Some may be more precise and say 'round brackets' for '()', 'square brackets' for '[ ]', 'braces' เบร ซีส for '{}'
Welcome to PSE and Happy New Year khun ภควรรณ
In reply to your "thank you",
I say "you are (very) welcome".
This is what we usually say when someone says "thank you".
Some other times we may say:
"it's a pleasure",
"Glad to be of some help",
"no worry",
"no problem" / "no problemo" (more American Hispanic style)
;-)
