📖 Read the story
Do you like video games or using a phone? These things work because of ‘Boolean’ logic. This sounds like a difficult word, but it is actually very simple. Boolean means a choice between only two answers. These answers are usually ‘yes’ or ‘no’. In math, scientists use the number 1 for ‘yes’ and the number 0 for ‘no’. Imagine your mom says you can have ice cream. But first, you must clean your room and do your homework. If you do both tasks, the answer is ‘yes’. If you only do one thing, the answer is ‘no’. Computers use this system to make big decisions. They ask many simple ‘yes’ or ‘no’ questions very quickly. This helps your phone and computer games work well. Every computer program uses this logic. It is a very important part of technology. Maybe you can use Boolean logic to build a program one day!
