This projects objective was for the end product to be easy to utilize, thereby facilitating mental math. Users operate it by adjusting different dials to create an equation; they then attempt to figure out the answer. Upon achieving the solution, users adjust the last two dials to display their answer. Custom Section Project: Mental Math Aide Objectives: By using this mathematical tool, you should anticipate an improvement in your mental math abilities or a substantial increase in proficiency in addition, subtraction, multiplication, and division. Audiences: The grades that will benefit most from employing this device are likely to be 1st grade through 3rd grade. Preparation: To utilize this project, there is no need for prior knowledge or additional resources; however, possessing glue would facilitate attachment of the two caps. Additionally, having some sort of sandpaper or file handy can assist with fitting components together if necessary. This device was designed to aid individuals with basic mental math. Operation begins by rotating the first dial to select a starting number. Next, users adjust the second dial to choose between addition, subtraction, multiplication, and division equations. Subsequently, users rotate the third dial to pick their second number for completing the equation. After performing the necessary arithmetic, users then rotate the last two dials to correspond with their calculated answer. For instance, when resolving a simple equation like 1+1 or 6-3, the result is entered on the last two dials as 02 and 03.
