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.

C. 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
D. How to say mathematical expression
25 + 352 = 377 Twenty five plus three hundred and fifty two is three hundred and seventy seven 45 – 56 = -11 Forty five minus fifty six is negative eleven
3 × 7 = 21 Three multiplied by seven is twenty one 24 : 6 = 4 Twenty four divided by six is four
43 = 64 Four raised to the power of three is sixty four or four cubed is sixty four
Ö625= 25 The square root of six hundred and twenty five is twenty five
3Ö64 = 4 The cube root of sixty four is four or the third root of sixty four is four 3Ö32 = 2 The fifth root of thirty two is two
x + y = 12 x plus y is twelve
x = y – 10 The value of x is equal to the value of y minus t x < y + 3 The value of x is less than the value of y plus three
