Business mathematics is like counting and solving puzzles for grown-ups who run businesses! Just like when you learned how to count your fingers and toes, adults use math to figure out how much money they have and how much they can make.
For example, imagine you were selling lemonade on a hot day. You need to figure out how much money you spent on lemons, sugar, and cups so that you can price your lemonade high enough to make a profit, but not too high that nobody buys it.
Also, imagine you have a store that sells toys. You need to figure out how much profit you make when you sell each toy. That means you need to subtract the cost of buying the toy from the amount of money you sell it for. You can use math to help figure out what to charge for your toys to make sure you're making enough profit!
Business math can also help people understand how much money they're paying in taxes or how much interest they'll have to pay if they take out a loan. It's kind of like being a detective and using clues to figure out how the money works in different situations.
So, business math is a very important tool for people who run businesses to figure out how much money they're making and how they can make more money!
