It depends on the function in question.
You can use the Math.pow function to raise one number to the power of another. Math.pow(24, 3) will return 243

Unlike in a true stroke, normal brain function will return with 24 hours
They don't have the same value! If, however, you were to say that |-24|=|24|, then THAT would be true, since the absolute value of any number is its distance from zero, and both -24 and 24 are 24 away from zero.

The twelfth even number and 24.
I suppose you mean "why do they have the same absolute value". This is because of the way the absolute value is defined. The absolute value is the "distance from zero"; it may help to look at the numbers on a number line to get this clear.

setInterval ( "increaseIntVal()", 86400000);function increaseIntVal( ){// (do something here)}
It could be: 2x+16 = -24 in which case the value of x is -20
