Without a calculator ? ! ? Are you aware that there were no calculators until just a few years before
people landed on the moon ?
Once upon a time, little kids used to learn how to add up numbers; the sharp ones could do it in their heads.
Going way back, anybody with a pencil and a flat piece of rock could have added 100 numbers.
The story you may be thinking of concerns the German mathematician Gauss, who supposedly added 1 - 100
in his head when he was 5 years old.
The big deal wasn't the addition. They had real schools in Germany at the time, and most 5-year-old German kids
could do that. The big deal was the easy shortcut that Gauss came up with.
Well the modern calculator with circuits was invented by William Seward Burroughs, while the first calculator (slide and rule) was invented by W. Oughtred (1574-1660).Nobody "discovered" the calculator in the contemporary sense. It was a natural outgrowth of continuous integrated circuit miniaturization.
Key in the dividend (the number to be divided) first to divide on a calculator, then key in the divisor after keying in the 'divided by' symbol.
First, you have to divide the numerator and then you have to divide the denominator.
The first calculator was never launched, because it was in fact a mechanical calculator.
The very first calculator ever used could be an abicus, an electronic calculator, or even your brain. The first calculator invented was the abacus.

Element number 6 was one of the first elements discovered, so it is not widely known who discovered it.
the first number discovered was I OR II (ROMAN NUMERALS) people first started to discover numbers by their hands or keeping track of their cattle first digit was '0'
First, you have to divide the numerator and then you have to divide the denominator.
you are the first person that first discovered, because suppose if you not a human being you wouldn't ask this question so you must considered that you discoveredd first.
Being able to work without a calculator will give you a deeper understanding of maths and arithmetic, and the methods (either using your brain or on paper) used to reach a correct answer. A calculator won't show you how to work the calculation, but will give an answer at the touch of a button or two. It is best to learn without a calculator first, before relying on a calculator.
It is prime. I have suggestion for you. Whenever you wanted to know a number is prime or not, use the calculator of this site: prime-calculator dot com.
Computers are first discovered by early humans. They use stones and sticks in adding or subtracting. Until 300+ BC, Chinese invented the abacus, the first calculator ever made.
The first calculator was never launched, because it was in fact a mechanical calculator.
First of all - this is is a MATHS question, not Technology ! Second - the answer (without the aid of a calculator... is 0.87 !
