About

Hello, my name is Lian and I am 9 years old. I like playing games and playing instruments. Today I am presenting my LEGO calculator project. I built a simple calculator using coding and LEGO. It can do basic math and follows the PEMDAS rule to solve problems in the correct order. I used variables in my code to store numbers and make calculations faster and easier. Variables help save time because you don’t have to repeat the same steps again and again. I made this project to learn more about math and coding, and I had fun building and testing my calculator.
