The Law of gravity was discovered by Issac Newton in which he described the inverse square of the gravitational force. However, gravity was understood by scientist and engineers long before Issac Newton. The fact that material bodies attract was well understood for several millenium, the mathematical equation that describe how was only discovered in the past couple of centuaries.
Another case is in terms of the postulate of relativity, in which the general description of a physical system is laid down before an actual equation is written.
Of course, one could say that math is used if one wish to quote the velocity of light as c(simple algebra) but stating that is irrelevant to the postulate. One could just talk about the velocity of light without referencing algebra or the actual measurement of the speed
light.
To say that the velocity of light is constant is to make a mathematical statement. A simple one - yes - but mathematcial nonetheless.
