When writing a formula, ""stands for "strength". For example, the square of three can be written as 3 2. Because superscript is usually difficult to enter, you can use 3 2 instead of 3? .

""is a mathematical symbol used to represent three-level operation. When inputting mathematical formulas on the computer, it is often expressed by power because it is inconvenient to input power. For example, the fifth power of 2 is usually expressed as 2 5.

On some calculators, this symbol is used to represent power. ' is a bitwise logical operator, and bitwise OR (Xor) is a reversible operator. Only when the two compared bits are different, the result is 1, otherwise the result is 0.

"∧" is different from "∧" and "",which means "and" and is a logical operator. For example, if A and B represent two conditions, then "A∧B" means "both satisfy A and B", that is, "A and B should be established at the same time". take for example

From typewriters to computer printers, there are no power symbols on them, and they all use ""as the power number: x 3 = x * x * x Today's computer keyboards still don't have the power symbols like typewriters. So we still use ""as a sign of power.

In fact, some computer languages (such as BABIC) still use the symbol ""as the official power number in programming.
