Solve Math Problems
Arithmetic operators are useful for doing calculations in your program. In this activity, we’ll focus on the basics:
- addition (+)
- subtraction (–)
- multiplication (*)
- division (/)
- modulus (%, the remainder of a division calculation)
Example project: simple_math
The example project simple_math uses the addition operator (+) to add the variables a and b together. The assignment operator (set c to) is used to store the result in the variable c. It also displays the result on the micro:bit.
- Enter, name, and flash the project simple_math to your micro:bit, then watch the display.
Your Turn – Experiment with Other Arithmetic Operators
You still have –, *, / and % to try out!
- In the project simple_math replace the addition (+) operator with the subtraction (–) operator. Be sure to replace both instances of + in the program.
- Re-flash the program to the micro:bit.
- Verify the result on the display.
- Repeat for the multiplication (*), division (/), and remainder of (%) operators.
