Part of a series of Mathematics videos starting with prealgebra. Covers basics of arithmetic operations, and basic vocabulary, as well as conventions for evaluating expressions with only one operation.
 What are the definitions of arithmetic operations, expression, equation, constant, variable, sum, difference, product, quotient, equation, natural (counting) numbers, and whole numbers?
 How do you simplify an expression with one operation?
 How do you simplify 10  8  2?
 What are some examples of an arithmetic expression?
 What is the difference between an expression and an equation?
 What are some examples of equations?
 What are some examples of constants?
 What are some examples of variables?
 What is the difference between a variable and an expression?
 What are some examples of natural or counting numbers?
 What are whole numbers and what is the difference between natural numbers and whole numbers?
 How do you find the sum of 8 + 1 + 3 + 10?
 How do you find the difference 29  14  3?
 How do you simplify 3 * 5 * 4?
 How do you simplify 100 / 5 / 5?
This lesson will teach you basic vocabulary involved in basic / preAlgebra math. Several different math terms are defined and discussed with examples given for each term. This is a great starting point for learning vocabulary terms or understanding them better. There are also some basic simplifying expressions with one operation in them at the end of the video.
