What do we use at the beginning of each body paragraph AND at the beginning of each new example in the bold paragraphs? WHY do we use those?

At the beginning of a paragraph we use an indentation, we use that to separate ideas or the body’s of whatever you’re writing make it more coherent just like the making of a new paragraph. Another thing we use is capitalizing the first letter of the word when we break apart a new paragraph just like when you start a new sentence.
