What is a Logarithm?
Note:
Logarithms can be tricky, but they become a whole lot easier if you understand how they're related to exponents. Follow along with the tutorial to learn about this relationship.
Background Tutorials
-
Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.
-
What are Positive and Negative Numbers?
Positive and negative numbers (and zero!) are the building blocks of math. This tutorial will introduce you to positive and negative numbers and show you their location on a number line. Plus, learn a special thing about the number zero!
-
-
Know and apply the properties of integer exponents to generate equivalent numerical expressions.
-
What are Exponents?
Did you know that another word for 'exponent' is 'power'? To learn the meaning of these words and to see some special cases involving exponents, check out this tutorial!
-
-
Use the properties of exponents to transform expressions for exponential functions.
-
What's an Exponential Function?
Looking at an equation with a variable in the exponent? You have an exponential function! Learn about exponential functions in this tutorial.
-
-
Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.
-
What are Inverse Operations?
Did you know that addition is the opposite of subtraction and that division is the opposite of multiplication? In fact, these opposite operations will undo each other! These types of operations are called inverse operations. Get a great look at inverse operations with this tutorial!
-
Further Exploration
-
Understand the inverse relationship between exponents and logarithms and use this relationship to solve problems involving logarithms and exponents.
-
What is a Natural Logarithm?
A natural logarithm is a logarithm that has a special base. In this tutorial, you'll be introduced to natural logarithms!
