The number 5 is the number of communication. In numerology, the number 5 helps convey the qualities of another number it comes into contact with. Generally, in Chaldean numerology, the numbers 1, 3, 5, and 6 are considered strong, while the number 9 is neutral. Numbers 2 and 7 can be overly sensitive, and numbers 4 and 8 are considered heavy and prone to difficulties. The number 5 typically helps to express the positive traits of strong numbers and the challenges of weaker ones.

Mercury (5), along with Venus (6) and the Sun (1–4), moves in such a way that it stays in relatively close proximity to these two planets. Among the strong numbers, 5 effectively communicates the favorable influence of numbers 1 and 6, as well as its own energy (the 5 and 5 relationship). Its relationship with number 4 is neutral—4 is not a strong number, yet it is still associated with the Sun. The interaction between 5 and 8 is generally unfavorable. The relationship between 3 and 5 is also usually unfavorable, even though both are strong numbers. So, the basic and most straightforward astrological criteria do not fully explain all aspects of these dynamics.
