Visual Order of Operations vs Multi Base Blocks Applications Uso e estatísticas
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

Multi Base Blocks Applications contains four apps to help young children proceed from the concepts of trading and place value through to the written algorithms for addition and subtraction. Preschool children can practice trades and learn about place value and grouping using the applications Win A Block and Trade A Block.
School aged children can use the applications Addition and Subtraction to bridge from performing the operations with blocks to carrying out the operations with symbols. On the same screen, students model the problem with multi-base blocks and are guided to perform trades and moves to arrive at the answer. While the students move the blocks, symbols are adjusted to match the student moves through to the final answer.
Parents or teachers can help children by making choices concerning grouping size, how many digits or columns in a problem, repeating a problem, creating a specific problem or generating a random problem. The applications are not intended to teach operations in another base, but to help children become familiar with the algorithmic processes so that they can more easily learn addition and subtraction in base 10.
