In mathematics, a number written in superscript is used to represent an exponent. In the case of x2, this can be read as "x to the power of two" or simply "x squared". An exponent is a way of noting how many instances of a value should be multiplied by itself. For example, 34 can also be expressed as 3 × 3 × 3 × 3.Here is a list of commonly used mathematical symbols with names and meanings. Also, an example is provided to understand the usage of mathematical symbols. x ≤ y, means, y = x or y > x, but not vice-versa. a ≥ b, means, a = b or a > b, but vice-versa does not hold true. .

In mathematics, the sum can be defined as the result or answer after adding two or more numbers or terms. Thus, the sum is a way of putting things together. In other words, the sum is the process of bringing two or more numbers together to produce a new result or total. Here, 5 and 7 are the addends and 12 is the sum of 5 and 7.P is a sufficient for Q. If P is true then Q will be always true (the first line in the table). Note that we do not consider the second line. But as we see in the table Q can be true also when P is false (the third line in the table). So P is "just" a sufficient condition for Q. Q is a necessary condition for P. It is obvious from the table.The modulo (or "modulus" or "mod") is the remainder after dividing one number by another. Example: 100 mod 9 equals 1. Because 100/9 = 11 with a remainder of 1. Another example: 14 mod 12 equals 2.
