👉 Guestbook math is a method for calculating the total number of guests attending an event by multiplying the number of guests per block by the number of blocks, assuming each block contains exactly one guest. For example, if there are 5 guests per block and 10 blocks in total, the total number of guests is 50 (5 x 10). This method simplifies counting but assumes uniform block sizes and does not account for varying numbers of guests per block or overlapping attendance. It's a straightforward, intuitive approach but can be less accurate in real-world scenarios with irregular block sizes or multiple guests per block.
