The equal sign in mathematics describes equality between the values, equations, or expressions written on both sides. The symbol for equal to is two small horizontal lines placed parallelly. We place the ‘equal to’ sign is between two things that are the same or equal.

What is the difference between equal and equivalent in math?
The difference between Equal and Equivalent
- Equivalent as an adjective: Similar or identical in value, meaning or effect; virtually equal.
- Equivalent as an adjective (mathematics): Of two sets, having a one-to-one correspondence; equinumerous.
- Equivalent as an adjective (mathematics): Relating to the corresponding elements of an equivalence relation.
What is an example of equality in math?
Example: 12 < x + 5. If we subtract 5 from both sides, we get: 12 − 5 < x + 5 − 5 . 7 < x. That is a solution! But it is normal to put "x" on the left hand side ..... so let us flip sides (and the inequality sign!): x > 7. Do you see how the inequality sign still "points at" the smaller value (7) ? And that is our solution: x > 7

What does the bracket mean in a set?
Without proper context, this is a bit tricky. However, the symbols “ {“ and “}” (curly brackets) are used to denote a set. Whatever is between them should be interpreted as elements of the set. So, in the first case, we have that the set contains “}” and in the second case, we have that the set contains “=”. In both cases, the sets contain exactly 1 element.

Can two integers be equivalent?
We can define different equivalence relations on the same set of objects. For example two integers could be equivalent if they are equal. Or we could say they are equivalent if they leave the same remainder when divided by 3 (equivalent modulo 3, e.g. 7 = 4 mod 3, 7 = 1 mod 3, 7 = -2 mod 3, 7 = -5 mod 3). And you could have equivalence modulo some other number too.
