no, not even close. it just depends on what you're trying to find.

No, theres millions of formulae.
s = d/t
V=IR (Ohm's law for calculating resistance, current or voltage of electric circuits)
F =mA (Newton's 2nd law for calculating the force, mass or acceleration of an object)

All these formulae can be manipulated to change the subject
For example :- F = mA

Divide equation by A:

F/A = m

ok for one i believe that is the formula for avg speed. speed equals distance over time. There are also ones that you can implement in physics like D=m/v which is density equals mass over volume. You can also use the circumference formula which is C= pi times the radius(squared). Also with shapes such as finding the area of a trapezoid (b1 + b2)H/2 or base 1 plus base 2 times the height, over 2

Actually there are essentially an infinite number of symbolic statements ( s=d/t), e.g. from physics for a body in free fall s = 1/2 gt^2, where the symbol  ^ means exponent, v = H d from astronomy for Hubble's Law, etc. Any statement that makes sense can be expressed in symbolic form by the proper definition of the symbols. Look in any physics, chemistry, mathematics book.

You can have an infinite amount of equations as equation can be derived from others.
