Together

FilledSmallSquareTogether[expr] puts terms in a sum over a common denominator, and cancels factors in the result.

FilledSmallSquare Example: Together[1/x + 1/(1-x)] LongRightArrow.

FilledSmallSquareTogether makes a sum of terms into a single rational function.

FilledSmallSquare The denominator of the result of Together is typically the lowest common multiple of the denominators of each of the terms in the sum.

FilledSmallSquareTogether avoids expanding out denominators unless it is necessary.

FilledSmallSquareTogether is effectively the inverse of Apart.

FilledSmallSquareTogether[expr, Modulus->p] generates a result modulo p.

FilledSmallSquareTogether[expr, Extension->Automatic] allows operations to be performed on algebraic numbers in expr.

FilledSmallSquareTogether[expr, Trig -> True] treats trigonometric functions as rational functions of exponentials, and manipulates them accordingly.

FilledSmallSquare See The Mathematica Book: Section 1.4.5 and Section 3.3.3.
