No Maths needed

I am driving my Daughter and Son back home from school.

“I bought some new colored pencils today”, says my Daughter.

How much was it? I asked.

it cost me only 4 Cedis. But I can see you are still holding the 10 Cedis I gave you this morning.

Yes, I gave my friend 10 Cedis and she returned it. She didn’t have change for me.

So did you return the pencils to her? No, I had already bought them.

So I think you owe her …. Daddy it doesn’t matter. Why so. Well you see Daddy, “I started with 10 Cedis and no colored pencils. I now have 10 Cedis with colored pencils”.

I don’t need to do any Mathematics 🧮
