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 / pre-Algebra 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.
