Hi,
I am a math tuition teacher. Now my students are preparing for their final exams. They are little slow in math problems. Actually i need to check the answers fast. So i tried many online calculators.
Finally found an online percentage calculator to calculate problems. But it is confused for me how it works and gives the result. Could someone explain me?
