Real Numbers. Any number such as positive integers, negative integers, fractional numbers or decimal numbers without imaginary numbers are called the real numbers. It is represented by the letter “R”. Examples: ¾, 0.333, √2, 0, -10, 20, etc.Ordering Real Numbers. Equality Symbols. You know what the equal symbol means and looks like. If a = b, then a and b are equal, (8 = 8). To learn about ordering real numbers, think about it this way. If a real number b is greater than a real number a, their relationship would look like this: b > a, and b is to the right of a on the number line Maths Math Article Real Numbers Real Numbers Real numbers are simply the combination of rational and irrational numbers, …These are symbols that is most commonly used in linear algebra. If x=y, x and y represent the same value or thing. If x≈y, x and y are almost equal. If x≠y, x and y do not represent the same value or thing. If x<y, x is less than y. If x>y, x is greater than y. If x≪y, x is much less than y.infinity, the concept of something that is unlimited, endless, without bound.The common symbol for infinity, ∞, was invented by the English mathematician John Wallis in 1655.
