In the mergers and acquisitions game, a buyer's math can be kind of strange -- that is, looking for a situation where 1+1 = 3. Unfortunately, the result is usually -3.

This is especially the case with mega deals, which involve mind-numbing complexities (especially with integration). In fact, the history of tech mega deals has been especially problematic.

Well, this doesn't seem to be an issue with the folks at Microsoft Corporation (NASDAQ: MSFT). They are willing to pay a whopping $44.6 billion for Yahoo!, Inc. (NASDAQ: YHOO).

So, can Microsoft make this thing work? Actually, the company's shareholders are skeptical. After all, the stock price is down $2.15 to $30.45. Keep in mind that -- based on various studies -- Wall Street is usually spot-on about these things.

Over the years, Dell Inc. (NASDAQ: DELL) has made only a handful of acquisitions. But as the company's market matures, this strategy doesn't make a lot of sense.

Well, we are seeing some signs that Dell is thinking about M&A.

This week, the company announced that it has agreed to shell out $340 million for ASAP software (in the past couple weeks, there was also a deal for Silverback Technologies).

Founded in the mid 1980s, ASAP provides IT services – helping customers "evaluate, purchase, deploy, and manage" software assets. Apparently, the company has much expertise in volume licensing.

As technologies get more complex, services become more important. So, ASAP should be a nice addition to Dell. It will also help with its competition against Hewlett-Packard (NYSE: HPQ) and IBM (NYSE: IBM).

According to Lindy Hanson, a senior analyst at Technology Business Research:

"Dell aims to use these acquisitions to engage with customers in new ways as of an overall effort to grow its services business. The company is building its managed services capabilities, one area it has not previously had a large presence in. I believe that, in growing its managed services business, Dell gains access to a larger pool of recurring revenue, in part from the ability to offer new services to its existing customers."
