Symbol B
B is one of the signed contributions combined to compute the quantity on the left.
Symbol I
I is one of the signed contributions combined to compute the quantity on the left.
Symbol E
E is one of the signed contributions combined to compute the quantity on the left.
Symbol L
L occurs above the fraction bar. The numerator is divided by the entire denominator below it.
Symbol N
N is one of the signed contributions combined to compute the quantity on the left.
=
The expressions on both sides represent the same quantity under the stated assumptions.
See an illustrated explanation →Denominator: 100
The complete quantity below the fraction bar; it must be nonzero for this division.

What the article says around this equation
Since Generation III, every non-HP stat in a modern Pokémon game is produced by one rule: take twice the species’ base stat, add its individual value (an inherited number from 0 to 31, effectively fixed for a competitively bred Pokémon [ 4 ] ), add the floor of its invested effort value divided by four, scale by level over 100 and round down, add five, then multiply by a nature coefficient of 0.9, 1.0, or 1.1 and round down again [ 1 ] : . HP uses the same inner term but a different outer shell, adding the Pokémon’s level plus ten instead of multiplying by a nature:
