A number without a variable. Ex.) 5 is a constant, 5x is not.
Constant just means that the number does not change. For example, in Chemistry, avogadro's number is 6.022x10^23 and that number will never change, therefore it is a constant.
I think that you are thinking of a math constant. A constant is something that doesn't change. The opposite would be a variable, which can change. For example: y=5 In this case, y always equals 5; so y is a constant. Second example; y=2x In this example, y is a variable, because its value depends upon the value of x. For example, if x=2, then y=4, but if x=10, then y=20.
It is the constant representing the ratio of the circumference of a circle to its diameter.

Constant is a number with no variables. For an example, 12a, but this is a constant 12.

In Math, something that does not change is called a Constant
In math, a number signified by "C" is a constant number. A constant is the opposite of a variable. While a variable changes, a constant will always stay the same. For example, in the equation y = 4x + 10, 10 is a constant. If you did not know the value of 10 (for example, if you had just integrated), it could be written as y = 4x + c.
Math is used mainly everywhere. For example in stores when there is a sale or your're paying for your item or at homewhen your're cooking or backing. Math is used mainly everywhere.

Mental math is basically math in your head so for example 40x2=80 so I did that in my head
The answer depends on what the constant is: the y-intercept in a linear graph, constant of proportionality, constant of integration, physical [universal] constant.
