Descrição
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

Avaliações e opiniões
Pretty good!
This app really helps with learning order of operations. It informs the student of when they are solving an operation in the wrong order and what should come first. It also tests their addition, subtraction, multiplication and division skills. It is possible though for a student to just click o the choices until they find the correct number. Really the only thing that bugged me about this app was that, in the rules section, it said that Exponents were the highest priority when really Parentheses were. When actually solving the problems, it said that parentheses came first. This could be confusing for some students.
Helpful!
The app helped my daughter understand the order of operations. Easy to use and understand. Thank you!
