Well, hello there, friend! 1.5E8 on a calculator is a way of writing 1.5 multiplied by 10 to the power of 8, which is also known as scientific notation. It's a convenient way to express very large numbers without writing out all the zeros. Just think of it as a shortcut to make working with big numbers easier and more manageable. Happy calculating!
