One traditional code beginners should always try is this: This will return “Hello World”. How it works The “print()” function returns whatever is inside it. Text inside the quotes will return whatever is inside it (things like print(f’1+1 is {1+1}’) will be explained later.) Try this one: Did it print…

A resistor is a device having a planned resistance to the passage of an electric current. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, and stop transmission lines. You can also calculate the value of a resistor. Here is the resistor color code: Color Digit…

The “9-trick”: To add 9 to any number, first add 10, and then subtract 1. Can you think of an easy way to add 76 + 99? Change it to 75 + 100. How about 385 + 999? How would you add 39 + 28 in your head? Let 39 become 40… which reduces 28 to 27. The…
