Yes, the terms 'multi-' and 'dual-' classing are somewhat irrelevant in 5e (and ever since 3e). You choose a class that you qualify for at each level, there is no statistic limitation but you need to meet any other requirements such as alignment. If you really want to play a Fighter-Wizard with 8 INT and 8 STR then you can. (EDIT: Turns out I am wrong here. You need a minimum 13 in the appropriate stats to qualify for a class, and 13 in both qualifying stats to multiclass. That's what comes of house-ruling too long).

You take all the 1st-level powers listed for the new class (not necessarily the same as a starting character of that class). Your character level then become the sum of all levels you have taken (so a 2nd level cleric/ 4th level fighter would have a character level of 6), but your class level is how ever many levels you have taken in the class in question (this determines such things as a wizard's spells). Some powers, such as Proficiency bonus, work off of the character level, and some off of the class level.

This method gives you a wider skill and power base, but you need to be wary of class restrictions such as wearing armour when casting wizard spells; something to consider before moving from an armoured class to to an arcane magic one.
