描述
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
