what does the sign that has a C and = over top of it mean in Algebra? Is it equals to or something else?

Jen,

Can you post symbols use in a problem? That may help us to identify it easier.

(3x-6)(x-8)(2x-7)=0;x C=natural numbers

Cand = are on top of each other.....

Jen,

I am still not quite sure what it is asking. But here are my thoughts.

In col 1, row 15 of this chart of Math symbols
(To find this chart, do a google search for "algebra symbols" and the 1st link should be off of gomath)

is shown the "is an element of" symbol,
which as I read your question would mean

Solve (3x-6)(x-8)(2x-7)=0 where x is an element of the set of all natural numbers (or in other words, the value of x is a natural number). I hope this helps.

Kenny,

Thank you for your help!

In algebra, the sign that has a "C" and an "=" over top of it is called the congruence sign. It is used to indicate that two quantities or expressions are congruent, which means they are equal or equivalent in some way.

To understand more about congruence in algebra, it's helpful to know a little bit about modular arithmetic. Modular arithmetic involves working with remainders.

When we write "a ≡ b (mod n)," it means that "a" and "b" have the same remainder when divided by "n." In other words, "a" is congruent to "b" modulo "n."

For example, if we have the congruence equation "7 ≡ 2 (mod 5)," it means that 7 and 2 have the same remainder when divided by 5. In this case, they both have a remainder of 2 when divided by 5.

So, the congruence sign in algebra (the "C" with "=" over top) is similar to the equals sign (=), but it specifically indicates congruence rather than regular equality. It is used to express relationships between numbers or expressions in terms of remainders.
