Adding_and_subtracting_decimals_word_problems

In this tutorial, we practice solving word problems by adding and subtracting decimal numbers.

Adding_decimals

Honestly, once you remember one very important rule, the rest of adding and subtracting decimals is a snap. That rule is to be sure and align your decimals first. In this tutorial, you'll get a chance to practice this with us and become fluent adding decimals. We'll tackle subtracting decimals in the next tutorial.

Dividing_fractions_by_fractions

Learn how to divide fractions by other fractions.

Subtracting_decimals

Just like with adding decimals, the key to subtracting decimals is aligning the decimal points. Let's practice!

Order_of_operations

In this tutorial, we learn the "order of operations" to evaluate more complex expressions involving exponents, parentheses, multiplication and division, and addition and subtraction.

Dividing_decimals

Learn long division with decimals. Solve problems like 30.24 divided by 0.42.

Dividing_whole_numbers

Learn long division on whole numbers. Solve problems like 9815 divided by 65.

Multiplying_decimals

You've already multiplied decimals in the 5th grade. We'll show you some ways to handle slightly more complicated problems. Now you'll become super good at it with a bit more practice! Common Core Standard: 6.NS.B.3

Exponents

In 3rd grade, you learned that there is an easier way to write "5+5+5". You saw that 5+5+5=3x5. But is there an easier way to write repeated multiplication (like "5x5x5")? Absolutely! That's exactly what exponents are for! Common Core Standard: 6.EE.A.1
