B. How to say number and symbols
Number forms | Number forms in English | |
1 digit number | 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 | zero, one, two, three, four, five, six, seven, eight, nine |
2 digit number | 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 30, 40, 50, 60, 70, 80, 90 | ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety |
3 digit number | 100, 300, 500, ... | one hundred, three hundred, five hundred, .. |
4 digit number | 2000, 4000, … | two thousand, four thousand, ... |
5 digit number | 10 000, 30 000, ... | ten thousand, thirty, thousand,... |
6 digit number | 300 000 | three hundred thousand |
7 digit number | 5 000 000 | five million |
8 digit number | 30 000 000 | thirty million |
9 digit number | 500 000 000 | five hundred million |
10 digit number | 2 000 000 000 | two billion |
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
Math expression | English 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 |
