Background Tutorials

Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (-1)(-1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real-world contexts.

Multiplying a whole number and a fraction can be confusing, but this tutorial helps to sort things out. Check it out!

Further Exploration

Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.

Word problems are a great way to see math in action! See how to create a table from the information in a word problem. Then use that table to write an equation and solve to find the answer.
