PENGUCAPAN OPERASI MATEMATIKA (1)
PENGUCAPAN OPERASI MATEMATIKA
Operasi penjumlahan
1+2=3
Untuk contoh penjumlahan di atas, ada berbagai cara untuk mengucapkan operasi bilangan tersebut.
Cara tersebut dibagi menjadi tiga yaitu : one plus two is three, one plus two equals to three, dan one
added by two equals to three.
Operasi pengurangan
2-1=1
Untuk pengoperasian perkurangan seperti yang sudah dicontohkan di atas, Anda bisa
mengucapkannya dengan beragam cara. Salah satunya adalah : two minus one is one. Selain itu, ada
berbagai cara lainnya yaitu two minus one equals to one, two less one is one, dan two substracted by
one is one.
Operasi perkalian
3x3=9
Sama halnya dengan contoh sebelumnya, jika pengoperasian bilangan matematika bisa diucapkan
dalam berbagai cara. Operasi perkalian pun memiliki cara yang bermacam-macam yaitu : three times
three is nine, three times three equals to nine, dan three multipled by three is nine.
Operasi pembagian
9:9=1
Untuk operasi pembagian sendiri, cara pengucapan operasi bilangan matematikanya adalah nine
divided by three is three. Cara lain dalam pengucapannya yaitu : nine divided by three equals to three.
Operasi pangkat
Dalam operasi pangkat, cara mengucapkannya cukup mudah. Contoh 2 pangkat 2 berarti bisa
diucapkan dengan cara : four squared is four.
Operasi akar
Sedangkan dalam operasi akar di bilangan matematika sendiri, Anda bisa menggunakan kata
‘squared root of’. Contohnya akar 9 adalah 3. Maka pengucapannya adalah : squared root of nine is
three.

How to say fraction
Generally, we can say a fraction sign (ex: a:b or a/b) with word ‘over’, for example:
a. 37:5 , it should be said as ‘thirty seven over five’.
b.3:7 , it should be said as ‘three over seven’
Note : The upper part of fraction called a numerator, the lower part of a fraction called a
denominator.
c. Some fractions already have a designated name, but the value of the numerator should not more than the value of
the denominator.
Example:
½ is half
x:3 is x-third; one-third, two-thirds, not five-thirds
x:4 is x-quarter; one-quarters, three-quarters, not seven-quarters
x:5 is x-fifth; one-fifth, two-fifths, three-fifths, not nine-fifths
