| Mental action . | Description of mental action . |
|---|---|
| Mental Action 1 (MA1) | Coordinating the value of one variable with changes in the other variable. |
| Mental Action 2 (MA2) | Coordinating the direction of change of one variable with changes in the other variable. |
| Mental Action 3 (MA3) | Coordinating the amount of change of one variable with changes in the other variable. |
| Mental Action 4 (MA4) | Coordinating the average rate of change of a function with uniform increments of change in the input variable. |
| Mental Action 5 (MA5) | Coordinating the instantaneous rate of change of the function with continuous changes in the independent variable for the entire domain of the function. |
