Hello! Recently I was in the store and I forgot my phone at home and I needed to calculate the cost of the product. So I thought about getting a percentage calculator next time. I think a lot of people need an interest calculator. Do you use one in stores or know how to calculate discounts in your mind?
I never even thought about that question. I wonder what other people have to say about it.
What app do you use on your phone to calculate discounts in stores? I understand that to find out the original cost you need to multiply the price at a discount by the percentage plus 1?
