In math, the symbol "=" is used to show that two values are equal. When two quantities or expressions have the same value, they are said to be equal to each other.
For example, in the equation 3 + 4 = 7, the "+" sign represents addition, and the "=" sign shows that the sum of 3 and 4 is equal to 7.
Similarly, in the equation 5 x 2 = 10, the "x" sign represents multiplication, and the "=" sign indicates that the product of 5 and 2 is equal to 10.
It's important to remember that the "=" sign is used to assert equality, meaning that the expressions on both sides of the "=" sign have the same value.
