In programming languages, the equals sign may either denote a boolean operator to test equality of values (sometimes a double equal sign "=="), or it may denote an assignment (sometimes denoted with a colon-equals ":="). In some programming languages such as PHP a double equals sign ("==") denotes equivalence, meaning that the variables may not be of the same data type, but their values can be reduced to the same value. The triple equal sign ("===") denotes identity, meaning that not only do the two values parse to be the same, they are of the same data type. For instance, in PHP the expression ("0 false") is not, because the number 0 is an integer value, whereas false is a Boolean.

Does everyone use algebra?
YES!! You use algebra in your everyday lives. Adding is considered an equation. An equation is a problem with an equal sign. An expression has no answer (an equal sign).
You use this symbol in an equation to indicate a sum?
An equal sign
What does 8 minus negative 3 equal?
8 minus negative three or 8--3 equal positive 11. The double negative converts the minus sign into a plus sign and the negative into a positive.
What do expressions which use numbers or other symbols and an equal sign mean?
In mathematics, such expressions indicate that the value of the expression to the left of the equal sign has the same value as the expression to the right of the equal sign. In some cases, it can also be interpreted to mean that the expression on one side of the equal sign can be used in place of the expression on the other side of the equal sign (say in manipulating algebraic expressions). In computer languages, the equal sign is sometimes also used to indicate that the value of the expression to the right of the equal sign is to be transferred to the location indicated by the expression to the left of the equal sign. The expression to the left of the equal sign is usually a single variable that represents a memory location.
Is at least algebra symbol?
At least means "greater than or equal to". In this browser it can be written as >=, but if you were writing with a pen, you would write the equal sign underneath the > sign, or even just double the lower part of the arrow.
