2) Two and two make four.

1) Two and two is four. = 2 and 2 is four. [spoken more than written]
The written form is: 2 plus 2 is 4. [arithmetic numbers, formal register]
2) Two and two make four. [informal speech, arithmetic]
"But Little Johnny, two and two make four, not five."
3) Two twos make four. [informal speech, not arithmetic, cards, for example]
Correction: Two twos make four. [plural nouns take a plural verb]
The plural of two is twos, just like threes and fours, etc.
"I have two twos, an ace and two kings." [poker, five cards per hand] "There are only three fours in this deck. One is missing." [cards] "How many twos and threes did they put in the mural?" [number two and number three]
Short answer should be deleted but since you ask only to explain third phrase
My understanding is that the first "two" examples are referencing addition whereas the third is an explanation that the same result is derived from multiplication but as in all things identical results are sometimes not equal.
The grouping was often said with a humorous air, and is a means to consider
2 plus (lots of) 2 (additive) make (is equal to) 4
2 (times) 2s (multiplied) makes (equals) 4
in addition it can be seen as a foreshortening of a fuller explanation
two twos makes for ? (thus a pun when said in context)
Singular and plural are both correct.
The singular form is also used because "two and two" is an arithmetic formula. The verb agreement in that case is with the formula as a single entity.
*Two and two makes four.
*Two plus two is four.
*Four times four divided by two is eight.
In your example in particular, Google indicates that the plural form occurs more often
