Addition and subtraction are inverse functions.
Inverse and idenity
Add together the coefficients of "like" terms. Like terms are those that have the same powers of the variables in the polynomials.
Addition, subtraction, multiplication and division
each individual part separated by addition or subtraction. ex: 3x2 + 5x + 7 has 3 terms, 3x2 and 5x and 7

Polynomials are the simplest class of mathematical expressions. The expression is constructed from variables and constants, using only the operations of addition, subtraction, multiplication and non-negative integer exponents.

The rules for addition are as follows:The sum of two negative integers is a negative integerThe sum of two positive integers is a positive integerThe rules for subtraction are as follows:If they are two positive numbers, do it normallyIf there is a negative and a positive ,change it to addition and switch the SECOND integer sign
PEMDAS RULE IS parentheses,exponent,multiplication,division,addition,subtraction
who discovered addition and subtraction.
In the United States, the acronym PEMDAS is common. It stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. PEMDAS is often expanded to the mnemonic "Please Excuse My Dear Aunt Sally". This explains the order of operations. With no brackets, exponents are resolved first, then multiplication and division from left to right, then addition and subtraction from left to right.
