Why did I build this?
Stem Cards is a project inspired by my son's middle school English teacher (Hat tip to Mrs. Wood!).
She encouraged students to make index cards with English word stems, meanings, and drawings. I observed how quickly my son learned this way and how fun it was to make and use those cards.
"I love this app! It's so easy to use and I can bring it with me everywhere I go. I'm learning so much!" - My 11yo son
"Sometimes, when we are eating out, our family tests each other with the quizzes. It's a fun way to learn and have family time!" - My friend
"In China, we used to memorize English words by heart. It was so hard! Now, with Stem Cards, I can learn English easily and fun!" - My friend in China
Now, with Stem Cards, you can learn like him. Explore English word stems, play with flashcards, and test yourself. It's fun and easy!

This math app is about the concept of order of operations. The user can evaluate random and custom expressions with exponentiation, division, multiplication, addition, and subtraction operations on integers and decimals. Operations can be grouped with nested parenthesis.
Expressions are evaluated one operation at a time just by tapping the operation. If the user taps an operation that can’t be solved next, the app tells why that was the wrong choice. There are no penalties for wrong answers.
After each step the solution for the current operation flies to the correct place. For example after solving 3 - 1 the answer 2 will fly to the correct place and the rest of the expression will move down. That way the user sees that only one part of the expression is solved in each step.
The user learns that the complexity of the initial expression does not matter because you only need to solve one multiplication, division, addition, or subtraction at each step.
The app uses a hierarchy of operators triangle - boss triangle - that shows the order of operations using a pyramid with exponent at the top, x and ÷ in the middle and + and - at the bottom. The rules are shown in a visual way instead of mnemonics.
Settings for random problems:
-allow multiplications
-allow divisions
-allow exponents
-allow negative numbers
-allow multi-digit numbers
-allow decimals
-allow parenthesis
-allow nested parenthesis
