If you have 54 balloons in each package and 18 packages, how do you find the total number of balloons?

Back

Multiply the number of balloons in one package (54) by the number of packages (18): 54 x 18 = 972.

What does it mean to represent a number in expanded notation?

Back

Expanded notation shows a number as the sum of its parts, breaking it down by place value, like 4 × 10,000 + 7 × 1,000 + 2 × 100 + 8 × 1 + 5 × 0.1.

Front

How do you find the greatest number of items you can make with a total amount?

Back

Front

What is the formula to find the total number of items when given packages and items per package?

Back

Total items = Number of packages × Items per package.

Front

How do you convert expanded notation to standard form?

Back

Add the values of each part of the expanded notation together to get the standard form.

Front
