Hi all! What is meaning of ^ symbol in math? Thanks for all help.

##### Share on other sites
It's used to represent exponentiation. So 2^2 means 22.

In math, X ^ Y means X to the power of Y.

2 ^ 3 = 8

If you are using a programming language be wary that may C-like languages use ^ to represent the bitwise XOR operation.

It can also be used as a hat above a symbol, which typically denotes a unit vector.

Thank you.

Guys, I am not proud of you today! the ^ symbol has nothing to do with the exponential in mathematics.

The ^ symbol represent the logical conjunction, or more simply the logical "and".

Having ^ represent the exponential is not a mathematical convention, it is a text formatting shortcut, probably started by latex. In latex, when you want to superscript something, you use "^{blah}", and "_{blah}" to underscript. But "^" does NOT represent the exponential in mathematical language.

Don't confuse the wedge (which this forum apparently doesn't like) with the caret (^). The use of the latter to represent exponentiation goes back to ALGOL.

It can mean that, in some contexts.

Fixed.

Depending on the context, it can mean any of the things mentioned.

Actually ^ does have to do with exponents and math.

For instance, when you're first taught exponents in school, they wont use the superscript method - they'll use ^. Kind of like how they use the x for multiplication until you start using a dot. ^ is a very valid and widely accepted means to denote exponent.

Maybe.

Teaching style varies just as much as notation does. That is: A lot.

There is no single answer to this. As Roboguy said, it depends on context.
