New Math (song)

"New Math" is a song that teaches us about a way of doing math that was introduced in the 1960s. It was supposed to be an easier way of doing math, but it was often confusing for people who were used to the old way of doing things.

The song has a lot of fast-paced lyrics that talk about the different rules and strategies for doing math in this "new" way. They use funny examples like "if you've got $2 and you go out and buy three apples, how many apples do you have?" which can be confusing at first, but it helps us understand how to apply the new math techniques.

Some of the concepts that the song talks about include breaking numbers down into smaller parts, called decomposition, and using symbols like + and - to represent adding and subtracting. It also highlights the importance of understanding the language of math, like knowing what "equals" means.

Overall, "New Math" is a fun and catchy way to learn about a different way of doing math that some people might find easier, but it can take some practice to get used to.
