In this learning activity you'll perform subtraction calculations using borrowing with mixed number fractions.

Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.

Users study a chart containing numbers 1 to 99 and look for trivial palindromes as well as double and triple iteration palindromes. The reverse and add technique is demonstrated.

Learners quiz themselves on the conversion factors within and between the metric, apothecary, and household systems.

In this activity you'll calculate equations using the order of operations. You'll be introduced to what it is and how it works.
