The coefficient appears in the monomial, and the number before the letter is called the coefficient. For example, the coefficient of 3a is 3, the coefficient of 5.8z is 5.8, the coefficient of -6b is -6, and so on. If there is only one letter, such as B, one 1 is actually omitted, that is, the coefficient is 1. The coefficient of y is 1. The coefficient of -a is-1.

Coefficient is the number factor in a single item, and degree is the index of letters in a single item!

For example, 4a 24 is a coefficient and 2 is a degree.

-6x 2-6 is the coefficient, and 2 is the degree!
