math error in readme

Summary

in math you don't write in this way the formula to be integrated:

(4.0/(1+x*x)) dx

adding "dx" at the end does have a different meaning: all the product is the differential area below the curve You sum in your integral. (and pls remove redundant braces and decimal point to 4..) So should be:

... the function, 4/(1+x*x), the answer is pi.
