Was that a pun? To soon to tail? Just got back from my 16 week ultrasound. Doc says she is positive the baby is a girl because she saw an equal sign.
Boy
The equal sign with the slash means "is not equal to".
By 'an equal sign with a lightning bolt [through it]', do you mean '≠'? That means 'not equal to'. For example, 6≠9.
It means the figures on either side of the equal sign have equal values to each other.
It means "not equal to".
not equal to
If you mean in Excel, yes: you must always start a formula with an equal sign.

Did you mean this? ≟
It means congruent
it means: "does not equal to" it mean that it is not equal to that, like 4a isn't equal to 5g. teehee!
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.
