What are the addition and subtraction coefficients, degrees and exponents of algebraic expressions in the first grade mathematics of People's Education Press?
The numerical factor in a monomial is called its coefficient. The sum of the exponents of all the letters in a monomial is called its degree. For example, the coefficient of abc is 1 and the degree is 3. In polynomials, the integer part of a term is called its coefficient, and the term without letters is called a constant term. For example, in the polynomial: 4ab-5c+6d -7,4,-5,6 are the coefficients of terms ab, C and D containing letters, while-7 does not contain letters, so it is called a constant term. Note: If there is no numerical coefficient in the formula, it defaults to 1 time, which refers to the sum of the indices of all letters in a single item.

In the power a n, where A is called the base, N is called the exponent, and the result is called the power, read "secret".
