FilledSmallSquare Together[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.

FilledSmallSquare Together 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.

FilledSmallSquare Together avoids expanding out denominators unless it is necessary.

FilledSmallSquare Together is effectively the inverse of Apart.

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

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

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

FilledSmallSquare See Section 1.4.5 and Section 3.3.3.

FilledSmallSquare See also: Cancel, Collect, Factor, PolynomialGCD.

FilledSmallSquare New in Version 1; modified in 3.
