These sets are equivalent. One thing you could do is write S = { x ∈ R: x ≥ 0 } just so that it is known that x 's are real numbers (as opposed to integers say). Another notation you could use is R ≥ 0 which is equivalent to the set S. Yet another common notation is using interval notation, so for the set S this would be the interval [ 0 ...

Interval (mathematics) The addition x + a on the number line. All numbers greater than x and less than x + a fall within that open interval. In mathematics, a ( real) interval is the set of all real numbers lying between two fixed endpoints with no "gaps". Each endpoint is either a real number or positive or negative infinity, indicating the ... Interval notation is a way to represent a set of real numbers on the number line. It consists of two numbers separated by a comma, and the numbers are enclosed in either parentheses or square brackets.

You will often find R + for the positive reals, and R 0 + for the positive reals and the zero. It depends on the choice of the person using the notation: sometimes it does, sometimes it doesn't. It is just a variant of the situation with N, which half the world (the mistaken half!) considers to include zero.R = the real numbers, thought of first as the points on a line, then many centuries later, after decimal notation had been invented, also as infinite decimals. Like the smaller set of rational numbers, the real numbers also form a field: arithmetic operations on real numbers always lead to real numbers. They were

If you moved it to the right, append "x 10 -n ", using the same logic. For example, the number 10,550,000 in normalized scientific notation would be 1.055 x 10 7 and 1.055e7 or 1.055e+7 in e notation.
