Terms

Exponents: a number placed above and after another

number or variable a number used to show the power the prior number or variable will be raised to.

or

Exponents

Variables: a quantity that is represented by a symbol

or letter assumes any given value or set of values.

(a, b, c, p, x, z, y, m, n)

or

Variables

Constants: A number or quantity placed before another

quantity A number multiplying another quantity Also known as a coefficient

or

Constants

Like terms: Terms where the constants and exponents

are alike.

****What is the solution?****7n³

Look for terms that are the same2n + 5n² - n – 3n²

2n – n are alike 5n² - 3n² are alike

Add or Subtract the constants

2n-n = (1)n 5n² - 3n² = 2n²

List in order by exponents

Final answer: 2n² + n

1) 8x + 6n 2) 6p + p3) 3n – 3n²4) 7z – 6z + 2z³

5) Identify the terms, variables, constants, and exponents in problems 2 and 4.

6) Why can’t some of these terms be combined?

Answer Box:1.8x + 6n2.7p3.3n – 3n²4.Z + 2z³
