The screen on my scientific calculator broke this week. So I was looking for a realiable online calculator I can use until I get a chance to replace mine. After testing several online calculators this one ticks all the boxes. It loads quickly, has a an appealing layout and displays what you have entered as well as the answer. None of the other online scientific calculators I looked at allowed you to see what you have entered and many of them were slow to load.
