1. \( 76593+45 \)

When you add \( 76593 \) and \( 45 \), you're essentially collecting the total amount of these two numbers, which can be thought of as stacking the numbers in a fun little mathematical tower! So, \( 76593 + 45 = 76638 \). It's like tiny numbers coming together to create a larger number celebration! A common mistake with addition is forgetting to align the digits correctly. For example, if you write \( 76593 \) and accidentally place the \( 45 \) in a way that mixes up the tens and units, you might end up with the wrong answer. Always keep those columns in line for a smooth addition party!
