1. What is the most common kind of real number?相关知识点: 试题来源: 解析 The most common kind of real number is irrational numbers. 实数分为有理数和无理数。虽然有理数在数轴上稠密,但从集合论的角度来看,无理数的数量远超有理数。因此,实数中最常见的类型是无理数。反馈 收藏 ...
Integers like −2, rational numbers/decimals like 0.5, and irrational numbers like √2 or π can all be plotted on the number line, so they are real. Better yet, they can be ordered. That means if we plot any two real numbers on the number line, then we know which one is to th...
real number Any of the rational numbers ( which include the integers ) or irrational numbers. Real numbers exclude imaginary numbers, found in complex numbers of the general form a +bi where i =√-1,although these do include a real component a. 相关知识点: 试题来源: 解析 实数 任何有...
A real number is any number that can be placed on a number line or expressed as in infinite decimal expansion. In other words, a real number is any rational or irrational number, including positive and negative whole numbers, integers, decimals, fractions, and numbers such as pi (π) and...

无理数(irrational numbers) 无理数,也称为无限不循环小数(如,π),不能写作两整数之比。 分数(fraction) 上面把分数分为了正分数和负分数,但还可以分为:真分数和假分数。 真分数(Proper Fraction):分子比分母小。 假分数(Top-heavy/Improper Fraction):分子比分母大。
such as 2.4871773339…. The real numbers include both rational numbers such as 42 and −23/129 and irrational numbers such as π and the square root of 2 and can be represented as points along an infinitely long number line. 不懂英文的可以看中文 实数 数学上，实数直观地...
rational number (for example, numbers $\frac{3}{2}$ and -2.4); irrational numbers (for example, numbers -√2 and π). All real numbers lie on the number line, so, they can be compared and ordered. If we can order real numbers, then we can add, subtract, multiply and divide real...
