    don't make it hard for people to help you, please make the example complete from documentclass to enddocument in particular you ask that it fits the margins without saying what size your page is..

Well, given that you introduce the two abbreviations, I suspect that you will agree with me that this equation is a bit bulky. I'd hence like to argue that the readers, and even after some months you yourself, will appreciate if you disentangle things a bit, which at the same time solves the issue.

I propose to use the medsize environment from nccmath, and alsp a variant with the multlined environment, instead of aligned. Note you don't have to load latexsym: its symbols are found in amssymb, and it's simpler to type ' rather than ^prime. For the integral with limits, you simply can pass limits as an option to amsmath.

    I propose to use the medsize environment from nccmath, and alsp a variant with the multlined environment, instead of aligned. Note you don't have to load latexsym: its symbols are found in amssymb, and it's simpler to type ' rather than ^prime. For the integral with limits, you simply can pass limits as an option to amsmath.

For the last 10-11 months, I am working in a research industry in France where my task is to debug C++ spaghetti code written over a period of several years by my current supervisor. It is a team of 2: just I and my supervisor. Diurnally, I am posed with a "bug of the day" to get out of this C++ code. My supervisor generally gives me about 15-30 minutes to solve it and then accosts me about whether or not the task is completed and then rinses and repeats this until the end of the day.

            Confectionery

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
