NumberLine

Number Line is a tool for illustrating simple numerical operations


Use this app when learning basic math operations such as addition and subtraction, division and multiplication. The app will be useful as an aid when studying negative numbers.
The app is easy to use: select an action, then numbers and get an illustration of how to solve this arithmetic problem
Addition (+), subtraction (−)
Start with the first number on the number line. Move by the value of second number towards the right (for addition) or left (for subtraction) and get an illustration of solved example
Multiplication (×)
Start at the first number on the number line. Every next touch on the number line will increase by 1 the second number. For example, starting at 3: 3x1=3, 3x2=6, 3x3=9, ...
Division (÷)
Start at the result (quotient). Every next touch will increase by 1 the second number (divisor). For example, starting at 3: 3÷1=3, 6÷2=3, 9÷3=3, ...
