Big O notation after the subroutine runs the algorithm must take an additional 55"n" + 2"n" + 10 steps before it terminates. Thus the overall time complexity of the algorithm can be expressed as "T"("n") = 55"n" + "O"("n"). Here the terms 2"n"+10 are subsumed within the faster-growing "O"("n"). Again, this usage disregards some of the formal meaning of the "=" symbol, but it does allow one to use the big O notation as a kind of convenient placeholder. In more complicated usage, "O"(...) can appear in different places in an equation, even several times on each side. For example, the following are
