What is the most useful about mathematics for human kind?

1 answer:

6 0

It's useful so when you go to the grocery store you know how much of whatever you need and you can multiply, divide, and subtract if needed. Without mathematics we wouldn't be able to calculate things. If you're a cashier for example, you need to know how to count change and count the money the person gives you. If you're a customer, you need to know how much to give the cashier and that involves mathematics. I hope this helped!!!
