4 IGCSE Data representation Denary to Binary Conversion 4

This video breaks down how to convert decimal numbers to binary, a crucial skill for IGCSE Computer Science. We'll explore the place value system in binary, explaining how each column represents a power of two, from the least significant bit to the most significant bit. You will learn a four-step method for conversion, starting from the left and determining whether each place value fits into the remaining number. Through clear examples like converting 75 and 200, you'll see this process in action, understanding when to write a 1 and subtract, or a 0 and move on. We also cover common mistakes to avoid, like forgetting to subtract or dropping leading zeros, and provide a simple method to check your work.
